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.
