Not tipping your waitstaff? That's cruel - that's part of their pay, which they need to get to minimum wage. Expect to be treated like dirt next visit. I would.
It might not be a great idea to frequent the place if that's your chosen form of social protest.
Tbh I think I got sick off my own food but I was doing the thing where I just honestly gave them all the info. I never really expected anything to come of it.
If the waiters or chefs hate your guts, at most they will swear in the kitchen.
