Wow, what a butthole-ish comment.
It’s not our, the customer’s responsibility to make sure waiters make minimum wage. So why do you demonize the customer instead of the business owner?
Everybody knows the rules of the restaurant business...wait staff gets paid less than minimum wage and work for tips. Anybody who takes advantage of that to keep a few bucks in his/her pocket by stiffing them and then lays it off as principled behavior is an asshole.
