That is fighting with the employer. Tipping is what the employers want. That's why my idea of "disobeying" was that this is when the movement to end US tipping culture makes sense. Europe has restaurants and they don't have a tipping culture.
I don't get why if I don't tip that I'm the one starving the employee, and not the employer.
"If you don't tip don't go out"? Telling people who want to see the tipping culture removed to not go out means that either way, the waiter doesn't get tipped. Europe has restaurants, so clearly tipping or not tipping doesn't dictate the existence of restaurants.
If a waiter works an entire shift and receives no tip, they are entitled to actual minimum wage instead of the reduced minimum wage. So there shouldn't be any moral misgiving to not tipping, it's just social pressure.
