I had an incident that happen to a group of us that went to dinner at a restaurant downtown owned by the Tres Carnales group concerning tipping. At the end of the meal everyone payed and left and me and my wife stayed for an extra drink, then asked for our bill afterwards. When our bill came we payed it and left a sufficient tip for the waitress, after the waitress left the manager stopped us before leaving the restaurant and questioned us about the tip we left?? He explained that he had a to tip out the waitress and the kitchen and that the tip left by the group was not sufficient. At first I was angry that the group didn’t tip properly but then I focused of the fact that tipping is not a mandatory item. So my question is whether tipping is mandatory and can a manager of a restaurant actually do what he did in this situation? Keep in mind that the minimum wage has gone up to $15 dollars an hour and that restaurants seem to be the only industry that tipping is mandatory. Its not like teachers, firefighters, police officers or retail workers expect a tip for helping you find something on a shelf or to find the size of jeans you wear. I’ve known a few waitresses that work at nice restaurants that make so much money on not taxed tips that they question changing professions.
