That why they said they don't go to restaurants with servers. Either go to a restaurant where you buy food at a counter and bus yourself, or go to a tipless resturant with servers. Obviously don't just screw over the server.

Though, on a large scale, if everyone just stopped tipping all at once, nobody would be willing to work for server wages anymore, and restaurants would have to increase pay or get fucked. Too bad our economy is based on fighting for survival, and not the profit motive, because the reality is that it would just fuck people's lives up really bad.
