I think you know what I mean here. I'm not saying don't have a drink in your bar, I'm saying don't get drunk beyond all common sense and decency in your own bar. You will never live the humiliation down.
Having said that, most of our bar staff have been highly intoxicated in my bar at some point while not at work - some more frequently than others. It's a bit like a spectator sport for the rest of the staff, and sometimes bets are even taken.
Unfortunately I joined these sorry ranks a few weeks ago - the bar staff are still making things up to tell me (at least I can't remember doing them - so they must be made up, right??)
