vouched this because it more or less matches my experience as a server. also want to second this point. do not "protest tipping" by refusing to tip employees who expect at least 15% to make ends meet. you're not making a point; you're just screwing over some random person.
also this ties into something that a lot of people don't seem to take into account when arguing for abolishing tipping. servers tend to like tipping. they don't enjoy the behavioral pressure, but they generally believe (correctly or not) that they make more money with tipping than they would in a counterfactual world without.
no one said anything about forcing and I don't currently work as a server. I'm strongly suggesting that not tipping doesn't make the point you think it does, and it definitely doesn't help that particular service worker. you're not pressuring the owner to change shit. you're sending home a low income employee with less than they reasonably expected to make off serving you dinner. servers who routinely complain about low/no tips tend to get fired (it's taken as a proxy for poor performance), not given a raise.
