Yeah… If you can’t afford the tip, then you can’t afford the meal. If you’re morally opposed to tipping culture, then don’t give money to the restaurants who rely on tipping.
Not tipping at a restaurant isn’t some revolutionary act, it’s just being a dick to workers. Waiters aren’t some sort of class betrayer, they’re just another worker being screwed over by management.
I don’t like tipping culture either, but at the end of the week that waiter is still going to have to pay rent.
