Effect on Restaurant Tipping of a Helpful Message Written on the Back of Customers' Checks

Research has shown that servers can increase their tip percentages by writing "Thank you" or by drawing a happy face on the backs of customers' checks. In the current study, a third approach of this type was tested. An experiment was conducted in which a female server either did or did not write a helpful message about an upcoming dinner special on the backs of checks before delivering them to customers. It was predicted that adding the helpful message would increase tip percentages because of reciprocity, in which customers would tend to respond to the server's "tip" with an increased tip of their own. Results were consistent with this prediction: Mean tip percentages increased from about 17% to 20%.     

Effect of Server's “Thank You” and Personalization on Restaurant Tipping1

Servers in restaurants frequently use the tactic of writing “thank you” on the backs of checks before delivering them to dining parties. Servers also frequently personalize their interaction with dining parties by signing their first name below the gratitude message. The effectiveness of these tactics in increasing tips was examined. In a field experiment conducted in an upscale restaurant in a large Northeastern city, a server wrote on the backs of the checks either nothing, “thank you,” or “thank you” plus her first name. The addition of “thank you” increased tip percentages, although personalization by adding her first name had no effect. It was concluded that the commonly employed low-cost tactic of expressing gratitude to customers by writing “thank you” on the check can produce a worthwhile return.     

Effect on Restaurant Tipping of Presenting Customers With an Interesting Task and of Reciprocity

Research has shown that servers can increase their tip percentages by positively influencing customers' mood and using the compliance technique of reciprocity. These factors were examined in the current study. An experiment was conducted in which a female server either did or did not present customers with a novel, interesting task that has been shown in previous research to stimulate interest and enhance mood. Additionally, sometimes she allowed customers to keep the task, in an attempt to elicit reciprocity. It was predicted that both of these manipulations would increase tip percentages. Presenting customers with the interesting task did increase tips, from about 18.5% to 22%, although the reciprocity manipulation had no effect.     

Effect of Beliefs About Future Weather Conditions on Restaurant Tipping

Research has shown that favorable weather is associated with increased tipping and that beliefs that weather is favorable can produce higher tips. In the current study, the possibility that beliefs about future weather conditions would affect tipping was experimentally examined. A server in a midscale restaurant wrote on the back of customers' checks either nothing, that the weather would be good the next day, or that the weather would not be so good the next day. Compared to writing nothing ( M = 18.73%) or giving an unfavorable forecast ( M = 18.18%), giving a favorable forecast ( M = 22.21%) resulted in significantly higher tip percentages. The power of beliefs, irrespective of their veridicality, regarding the state of atmospheric conditions in affecting human response is discussed.     

Relationships of smiling and flirtation to aggression and 2D:4D, a prenatal androgen index

Smiling has been reported to be a signal of submission/lower status, or a sign of cooperation. In the present study, use of smiling and flirtation to "make people receptive to my ideas" was conceptualized as mild aggression, since it is mildly manipulative of the perception of others as to one's internal emotional status. For 91 participants (55 female, 36 male), use of smiling and flirtation to make others receptive to one's ideas were associated with relational aggression and a more male-typical (smaller) right 2D:4D finger length ratio. The only significant relationship in the male sample alone was the relationship between smiling and relational aggression. In the female sample alone, use of smiling and flirtation to "make people receptive to my ideas" was associated with a more male-typical 2D:4D finger length ratio pattern, and there was a trend for flirtation to be associated with greater physical aggression. Both 2D:4D and physical aggression have been associated with higher prenatal androgen level. It is concluded that deliberate smiling and flirtation are mild forms of relational aggression, and are related to prenatal androgenic activity in a manner similar to physical aggression. These findings are discussed in terms of the different evolutionary strategies of men and women to control their social environments.     

Attributions of guilt and punishment as functions of physical attractiveness and smiling

The authors found an interaction between sex of participant and sex of defendant in the leniency bias toward a smiling defendant. Differences occurred for male participants when levying punishment for a smiling male defendant vs. a smiling female defendant and for a smiling male defendant vs. a nonsmiling male defendant, whereas differences did not occur for female participants. The authors found moderating effects of physical attractiveness and smiling between guilt and punishment. The only significant positive relationship between guilt and punishment occurred for the defendant whom participants rated low in physical attractiveness and who was not smiling. When guilty, the smiling and unattractive defendant received less punishment than did the smiling and attractive defendant. The authors discussed complex relationships between physical attractiveness, smiling, guilt, and punishment.     

Smiling in photographs: childhood similarities between sexes become differences constant in adulthood

Contemporary published photographs of 1639 children, 200 older teenagers, and 304 adults in North America were analyzed for the smiling pattern (full, partial, or none) exhibited by individuals by sex. For each of the three age groups and for both sexes, most individuals posed with a full smile. No statistically significant differences in smiling pattern were present between the sexes for photographs of children at preschool and grade-school age. By teenage years, and even more for the adults, there were statistically significant differences between the sexes with regard to a smiling facial expression. In those cases, more female than male subjects smiled fully, whereas more male than female subjects did not smile. Examination of photographs of well-known persons longitudinally through adulthood showed that individuals tended to be consistent in smiling pattern. There was no significant sex difference for this relative constancy of facial expression in posed photographs.     

Relations between emotions,display rules,social motives,and facial behaviour

We report research on the relations between emotions, display rules, social motives, and facial behaviour. In Study 1 we used a questionnaire methodology to examine how respondents would react to a funny or a not funny joke told to them by a close friend or a stranger. We assessed display rules and motivations for smiling and/or laughing. Display rules and social motives (partly) mediated the relationship between the experimental manipulations and self‐reported facial behaviour. Study 2 was a laboratory experiment in which funny or not funny jokes were told to participants by a male or female stranger. Consistent with hypotheses, hearing a funny joke evoked a stronger motivation to share positive affect by showing longer Duchenne smiling. Contrary to hypotheses, a not funny joke did not elicit greater prosocial motivation by showing longer “polite” smiling, although such a smiling pattern did occur. Rated funniness of the joke and the motivation to share positive affect mediated the relationship between the joke manipulation and facial behaviour. Path analysis was used to explore this mediating process in greater detail.     

Effect on tipping of barman drawing a sun on the bottom of customers' checks

Previous research has demonstrated that a pleasant drawing (a smiling face) on a restaurant bill increased the number of tips left by clients. A similar experiment was carried out using a drawing of the sun since it is known that tips increase on sunny days. The experiment was carried out in local bars and involved clients who have ordered an espresso coffee. Analysis showed that the drawing of the sun led clients to leave a tip more frequently than when this drawing is not present. The size of the tip left was also higher. The hypothesis of the creation of a positive frame of mind by this stimulus is discussed.     

Smiling faces rated more feminine than serious faces in Japan

It has been reported that women and girls smile more frequently and more effectively than men and boys. It is expected that this correlation between femaleness and smiling affects the processing of faces, and consequently, smiling faces may be perceived to be more feminine. Participants viewed 30 photographs featuring smiling and serious facial expressions of both male and female subjects and rated them for femininity or masculinity. The result indicated that smiling faces significantly more frequently gave the impression of being more feminine. The interaction between the sex of the faces and their expression was not significant.     

An experimental approach to the use of ingratiation tactics under homogeneous and heterogeneous dyads

The present research investigated the occurrence of ingratiation as mediated by the sex of sender and recipient in a 2 × 2 × 2 factorial design and also explored the underlying structure and preference of ingratiation overtures. Subjects were instructed to enact the role of interviewees and were motivated either to make themselves amiable or to act spontaneously to improve evaluation accorded by the interviewer. It was hypothesized that ingratiation behaviours would be distinguished from spontaneous behaviours for the investigated opinion conformity, self-presentation, other-enhancement and smiling. These main effects were found and specified by the sex variables in the expected direction with modesty as an ingratiation tactic under the female homogeneous dyad, more ingratiation overtures under the heterogeneous than homogeneous dyads on some verbal measures, and less ingratiation smiling under the male homogeneous dyad. Further, verbal and nonverbal overtures were shown to possess a different structure, and a multivariate analysis of variance revealed opinion conformity to be the most sensitive differentiator between the verbal ingratiation overtures. The discussion deals with the search for the subtleties in ingratiation messages and emphasizes some provocative findings.     

Mimicry for money: Behavioral consequences of imitation

Two experiments investigated the idea that mimicry leads to pro-social behavior. It was hypothesized that mimicking the verbal behavior of customers would increase the size of tips. In Experiment 1, a waitress either mimicked half her customers by literally repeating their order or did not mimic her customers. It was found that she received significantly larger tips when she mimicked her customers than when she did not. In Experiment 2, in addition to a mimicry- and non-mimicry condition, a baseline condition was included in which the average tip was assessed prior to the experiment. The results indicated that, compared to the baseline, mimicry leads to larger tips. These results demonstrate that mimicry can be advantageous for the imitator because it can make people more generous.     

The effects of smiling on perceived age defy belief

It is a common belief that smiling makes people appear younger. Empirical findings, however, suggest that smiling faces are actually perceived as older than neutral faces. Here we show that these two apparently contradictory phenomena can co-exist in the same person. In the first experiment, participants were first asked to estimate the ages of a series of smiling or neutral faces. After that, they were asked to estimate the average age of the set of neutral and smiling faces they had just evaluated. Finally, they were asked what effect smiling has on one’s perceived age. In the experimental session, smiling faces were perceived as older than neutral faces. Nevertheless, after the experiment, consistent with their retrospective evaluations, participants recalled smiling faces as being younger than the neutral faces. Experiment 2 replicated and extended these results to a set of emotional expressions that also included surprised faces. Smiling faces were again perceived as older than neutral faces, which were in turn perceived as older than surprised faces. Again, retrospective evaluations were consistent with the belief that smiling makes people look younger. The findings show that this belief, well-rooted in popular media, is a complete misconception.     

The Effect of Patriotic Messages on Restaurant Tipping1

This study compared the effectiveness of 2 types of patriotic messages with a warmth/ ingratiation message and a control condition on restaurant tipping. Two female food servers waited on 100 parties eating dinner. When diners were finished with their meals, servers left them 1 of 4 messages on their checks: “Have a Nice Day,”“God Bless America,”“United We Stand,” or no message. Results indicated that parties who received the “United We Stand” message left significantly higher tips than did those receiving no message or the “Have a Nice Day” message. No other significant differences were found. These results and their implications are discussed.     

Social context effects on facial activity in a negative emotional setting

Evidence for A. J. Fridlund's (e.g.. 1994) "behavioral ecology view" of human facial expression comes primarily from studies of smiling in response to positive emotional stimuli. Smiling may be a special case because it clearly can, and often does serve merely communicative functions. The present experiment was designated (a) to assess the generalizability of social context effects to facial expressions in response to negative emotional stimuli and (b) to examine whether these effects are mediated by social motives, as suggested by the behavioral ecology view. Pairs of friends or strangers viewed film clips that elicited different degrees of sad affect, in either the same or a different room; a control group participated alone. Dependent variables included facial activity, subjective emotion, and social motives. Displays of sadness were influenced by stimulus intensity and were lower in all social conditions than in the alone condition. Unexpectedly, social context effects were also found for smiling.     

Male responses to female competence

This study investigated the conditions under which a male would denigrate a female because of her competence. Sixty-four male subjects either cooperated or competed on anagram tasks with high/low competence male or female co-workers in the presence of a male or a female experimenter. Subsequently, these subjects evaluated their co-workers. No evidence was found to support the notion that males rejected a female partner because of her competence. In fact, some measures revealed that competent females were valued over their male counterparts in the cooperative conditions. Unexpectedly, sex of the experimenter interacted significantly with sex of the co-worker to determine the subject's responses to his partner's competence on two of the dependent measures. The discrepancies between these findings and earlier research findings are addressed. The implications for females in a mixed-sex work context are discussed.     

The contingent smile: a meta-analysis of sex differences in smiling

The authors present a meta-analysis of sex differences in smiling based on 448 effect sizes derivedfrom 162 research reports. There was a statistically significant tendency for women and adolescent girls to smile more than men and adolescent boys (d = 0.41). The authors hypothesized that sex differences in smiling would be larger when concerns about gender-appropriate behavior were made more conspicuous, situational constraints were absent or ambiguous, or emotion (especially negative) was salient. It was also predicted that the size of the sex difference in smiling would vary by culture and age. Moderator analysis supported these predictions. Although men tend to smile less than women, the degree to which this is so is contingent on rules and roles.     

Persuasion by Way of Example: Does Including Gratuity Guidelines on Customers' Checks Affect Restaurant Tipping Behavior?

This study examined the role of gratuity guidelines on tipping behavior in restaurants. When diners were finished with their meals, they were given checks that either did or did not include calculated examples informing them what various percentages of their bill would amount to. Results indicated that parties who received the gratuity examples left significantly higher tips than did those receiving no examples. These results and their implications are discussed.     

Status,Gender, and Nonverbal Behavior in Candid and Posed Photographs: A Study of Conversations Between University Employees

Ninety-six male and female university employees (93% White, 6% African American, 1% Asian) were photographed in dyads while they conversed about working at their university (candid photographs) and again while they deliberately faced the camera (posed photographs). Eight nonverbal behaviors were coded from the photographs, and relative status was ascertained from a postexperimental questionnaire. Status differences were found for upward (chin-up) head tilt and for resting elbows on leg or furniture; candid versus posed differences were found for upward head tilt, smiling, and raising the eyebrows; and gender differences were found for smiling, erect posture, forward lean, and touching self. Interactions involving gender, candid/posed photographs, and/or status suggested limitations to generalizations about main effects.     

The Effects of a Joke on Tipping When It Is Delivered at the Same Time as the Bill1

Former studies showed that a cartoon, such as a smiling face or a cheerful drawing (i.e., the image of the sun), increased the amount of tips given by a customer when added on a bill. A replication was made in accompanying the bill with a small card on which a joke was appended. The experiment took place in a bar with people who had had the same drink. The results showed that people who received the joke card were more likely to tip than were people in the control condition or in a condition where an advertisement card accompanied the bill. The size of the tips left tended to be higher in the joke‐card group than in the other conditions. The findings are discussed in terms of the positive mood activated by the joke card, which in turn increased tipping behavior.
