> Then they'd quit working for minimum wage

I see no reason to think that was the case. They'll work for whatever rate companies pay them. There are many workers in minimum wage jobs who don't get tips at all. I agree that tipping is a bad practice and that it pushes labor costs onto customers. It will take regulation for companies to stop and tipping culture to change. I'm doing my part to try and keep the problem from getting worse by refusing to tip for almost anything except deliveries and being actually waited on. No matter how much companies beg for tips for basic retail purchases and counter service I don't feel at all bad about turning them down.
