yea kinda want to add on to this for any non-American who's reading this thread. i've lived in the US my whole life and i've never heard of someone getting confronted by security for not tipping. restaurants usually don't have security so you wouldn't run into that issue there. clubs and some bars would have security but i've never heard of them having to track people down for not tipping.

i've just seen servers get annoyed that they didn't get tipped but they don't go after the customers or anything like that.

I've worked security at a bar, and servers and bar tenders bitched about not getting tips, but never would it ever cross any of our minds to get security involved.
