Modern Manners

Philip Howard answers your questions on contemporary etiquette (礼仪)

Philip Howard,

When my friend and I (two ladies of a certain age) go out to have a meal, she always leaves an extremely large tip. At times, the tip will equal the amount of one of the main dishes—sometimes it comes to about 30 per cent of the bill. I feel 15—20 per cent is adequate for services offered and depending on the type of restaurant. At a cafe I would like to leave 15 per cent or a bit more depending on the service and etc. A larger tip would be appropriate if we are in a big city or a nicer place. My friend says “Well, I am sure they are not driving a Mercedes (奔驰汽车).” Well, neither am I, and how does she know? Who is correct and how can I make changes? I might add I do truly feel tipping should be based on good service, and also if you frequent a place and know the staff a larger tip is OK. I would never hesitate to tip a waitperson. I always leave to the higher side.  

     Yours,

                                      Barbara Bade

Barbara Bade,

Americans are more generous tippers than the British. I suspect that 10 per cent for a tip is about normal in the UK. Tipping is a strange survival in our age of supposed equality and minimum wages. Your friend has a generous nature and deep purse. I do not see why you cannot let her tip whatever she wants, and do your own thing. I agree that a tip should be a reward for good service and general good feeling. If the service is rotten and the meal a disaster, we should withhold a tip and explain why we are doing so. Few of us have the chutzpah (厚颜) to do this. Sensible restaurants have a box for tips, so that they are shared out among the staff, including those in the kitchens whom we do not see. (I trust that the management does not receive the money as extra profit.) I look forward to the day when waiters and other servants are paid a good enough living wage, so that they do not have to depend on the generosity of strangers to survive. To wait at table is just as honorable a way to earn a living in this wicked world. If you are pleased with the meal and cheerful service, you should tip as handsomely as your purse affords. I don’t suppose that your waiter / waitress is driving a Mercedes, even in the States. 

Yours,

Philip Howard
