I agree that if at any point you suspect the pricing isn't fair in any transaction, it's up to you to leave. If someone checks Yelp and sees red flags on tipping but still decides to go and complain about it, they're being a jerk.
But many sit-down restaurants don't give any indication about the tipping procedures until after a meal is served and consumed.
so instead of tipping zero, since that implies the ability to decide, tip something that might be less jerk and make the decision to not return, perchance?
and if you aren’t given a choice, and it isn’t advertised, well, that’s a different predicament. same solution. you aren’t going to refuse to pay, so refuse to return.
