Research goals Owing to variations that existed previously on the number of tips given by different hotel customers; depending on whether the serving waiter showed gratitude by writing thank you on the back of checks or smiling when presenting such checks, researchers conducted this research to ascertain impacts resulting from drawing of smiling faces on the back of the checks. In addition, researchers conducted this investigation to ascertain differences that might occur when individuals of different sexes presented to customers checks, which had smiling faces drawn on their backs. This is to say, the second experimental goal was to determine different individuals’ perceptions as pertains to some acts that they consider appropriate for female servers and not appropriate for male servers. Generally, the experiment was to contrast variations in terms of tips that waiters were to receive by presenting checks with or without smiling faces drawn on the back of such checks, depending on the sex of the waiter (Rind & Bordia, 1996, p. 1). Independent and Dependent Variables Because the researchers’ main aim was to determine influences that smiling faces drawn on the back of the checks had on the number of tips offered by the customers depending on the sex of the attendant, the dependent variable is the amount of tip that each customer was to offer. On the other hand, because the amount of tip depended on who presented the check and whether the check had a smiling face drawn on it, the independent variables were the drawing of a smiling and happy face, which some checks were supposed to have, and the sex of the attendant. It is important to note here that any factor under investigation never alters the independent variable, but rather its effects determine the nature of the outcome. Participants The participants of the research were members of the temple university fraternity, which comprised of the faculty, students, other university workers, and two restaurant attendants; one male and another a female whose age range was in the mid-twenties. In number, the participants were one hundred and ninety-three, who comprised of eighty-nine parties that had taken their lunch in the eatery, in a time span of three days (Rind & Bordia, 1996, p. 220). Procedure To achieve desired outcomes, the researchers conducted their research applying the following procedure. Firstly, the experiment was to take place within a time span of three days; Monday to Wednesday, whereby each server had to have fifty cards; some with the drawing of the smiling and happy face (twenty-five), and another bunch without the drawing (twenty-five also). To ensure there was even distribution of the cards; hence, ensure randomness, the two attendants had to mix the cards by reshuffling them. After doing all this, the second step was for the attendant to give the check to the party. However, before presenting the check as rules dictated, they had to take pick a single card from their pockets randomly; hence, determining whether they were to sketch the smiling face or not on the back of the check that they were about to present. When presenting the check, the attendants had to ensure the drawing on the presented checks were visible to the party; hence necessitating the presentation of the check to
