Seriously?! That's very insulting
Insulting to who? We are polite and tip well, we just don’t want to chat. I doubt the bar staff do either, but they feel they have to. I spent many years as a barmaid and didn’t like the forced smalltalk with regulars when I was on that side of the bar either.
Some random old woman plonked herself down at our table while we were eating a couple of months ago, and started chucking DS1’s chin and cooing at him. He rolled his eyes and blew a raspberry. I knew exactly how he felt!
