Because the restaurant wants to under pay their employees and have you pay them directly instead.

It's a way of marginalizing the working class. People being annoyed at tipping translates into the owner saying "well I'll have to raise prices then because these darn mongrels and their stupid silly basic needs cost money."

They want you to resent the working class. That's the reason.

Yeah, I ran into one of these owners. This person said it is not their responsibility to make sure their employees can afford necessities while working for them full time.
