Studies in restaurants show that the tips left by customers who pay their bill tend to be larger when the bill is presented with the server’s name hand-written on the bill. Psychologists hypothesize that simply seeing a handwritten name makes many consumers feel more of a personal identification with the server, encouraging larger tips.

Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies?


(A) The effect noted in the studies applies to patrons paying with either credit cards or cash.

(B) Nametags for servers have not been shown to have any effect on the size of the bill.

(C) Greeting card companies have found that charities which send holiday cards with and written signatures are more likely to receive donations than those which send cards with printed signatures.

(D) The studies indicated much larger average tips if the customer ordered alcoholic beverages with his or her meal.

(E) Many of the restaurants in which the studies were conducted are located in tourist areas, where people are traveling for leisure activities.
