Bro they are working in a high intensity environment. You are there to have fun. They are talking behind your back. (So how does that affect you?) Versus actively being a jerk to someone just doing their job (which is, unfortunately, to engage with you). It’s not the same.
Are you really trying to explain running a bar to me? Anyways your answer is horseshit. I work in that high intensity environment and see the blinders go on. Innocuous requests by customers turn into staff acting like it’s a massive imposition. They openly talk to me because they’ve been at my bar, served by me, and I know who’s I’d hire and I wouldn’t from the free talk.
