Question: I am writing to ask you about the practice of tipping as it relates to three situations that are outside the realm of conventional dining:
The first occurs in a sushi bar, where the preparer and server of the meal are one and the same. I have noticed glasses sitting on the bar, similar to those used by bartenders to promote gratuities. Is a tip here a given, or is it optional?
In addition, when a different person serves beverages and presents the check, should this person also receive a gratuity? If a credit card is used, which of these people benefits?
The second situation has to do with Chinese dim sum, which involves the delivery of the various foods to the table by several different waiters offering selections from carts. Again, there is a beverage server. Who merits a tip, and for what amount?
The third instance is the breakfast buffet, during which the waitress' only service to the patron is to pour coffee. Surely she is not entitled to the usual 15 to 20 percent tip.
I hope you can offer some guidelines, so that I do not inadvertently slight anyone who has provided service.
Answer: Unless you obtain a copy of the work schedule of the restaurant, and also make it your business to do a study of the performance level of each employe, you will never reach that godlike goal of distributing rewards exactly according to deserts. Or sushi. Or dim sum.
Miss Manners advises you not to try. Put your 15 or 20 percent tip on the bill, regardless of the type of restaurant or service, and let the restaurant worry about distributing it.
Each of the people you mention is on full working duty during your meal, and worrying about how hard they actually work will only upset your digestion.
