/ck/ - Food & Cooking

We've had tipping threads on /ck/ before. But we've never had a NOT tipping thread.

What's the best way to not tip? I tried to not tip tonight, but the waiter wouldn't take my card. As in they literally would not process it until I wrote something down in the tip line. I put some small amount, like 5-10%, just to not cause a scene. But I'm thinking there's a better way to.. not tip.

Also would waiters actually spit in my food and whatnot if I continued to do this?
