### HideShow timer Statistics

In a study conducted in Pennsylvania, servers in various restaurants wrote “Thank you” on randomly selected bills before presenting the bills to their customers. Tips on these bills were an average of three percentage points higher than tips on bills without the message. Therefore, if servers in Pennsylvania regularly wrote “Thank you” on restaurant bills, their average income from tips would be significantly higher than it otherwise would have been.
Which of the following is an assumption on which the argument relies?
A. The “Thank you” messages would have the same impact on regular patrons of a restaurant as they would on occasional patrons of the same restaurant.
B. Regularly seeing “Thank you” written on their bills would not lead restaurant patrons to revert to their earlier tipping habits.
C. The written “Thank you” reminds restaurant patrons that tips constitute a significant part of the income of many food servers.
D. The rate at which people tip food servers in Pennsylvania does not vary with how expensive a restaurant is.
E. Virtually all patrons of the Pennsylvania restaurants in the study who were given a bill with “Thank you” written on it left a larger tip than they otherwise would have.

(A) is incorrect because it expresses a difference between the regular and occasional patron, but here in the question stem we are looking for the assumption BASED on the premise given.(C) states that the importance of occasional "thank you" will loose value if all the bills start containing a thank you message.
(B) wins

Is passage talking about old patrons and new patrons and their trends on tipping? If not, B is not making much sense.

C looks more appropriate to me, as it talks about only patrons who understand the significance of tips on the livelihood of servers.

that been the condition then the patrons really do not need thank you messages to pay tip(which is common )

'A' - It is classifying the customers. - Out of scope.
'B' - it is clearly saying and strengthening the argument. as author has study the mind of the customers and he has read some report which says recident of Pennsylvania will continue there habbit. - So it the best.
'C' - If the "thank you" reminds the customers that they have given heavy tip, then will it make any difference to restaurant owner? I think not. So 'C' is out
'D' - Out of scope. as it is not tell any thing about increasing / decreasing of income from TIP.
'E' - Out of scope. as it gives blame on the restaurant itself.
