Good servers are constantly questioning their guests: Would you like a cocktail before dinner? Is your steak cooked correctly? Are you considering dessert this evening?
But restaurant etiquette dictates that the questions stop as soon as the check's dropped. No matter how lousy the tip, servers aren't supposed to ask their guests whether they could have done anything to make their experience better – even if the phrasing's exceedingly polite.
Staying mum isn't easy, especially since servers are trained to make sure their guests are happy. A poor tip doesn't seem too different from a restaurant goer yelping, "I'm having a terrible time!", a cry no capable server would ignore.
