The bartender needs to assume full responsibility....It's just that simple in every bar I've ever worked at, thats been the rule, you need to go above their head, and speak with the owner, and head bar keep about this....

In my experiance, the bartender always (or atleast should) appreciate all the help they can get...And cutting someone off is a hard decision...The sooner you cutt someone off the more money you loose from that one customer....HOWEVER, I've seen bars go OUT OF BUSINESS, if not from the state, but from the majority of customers who would rather drink somewhere else where they cut loosers off before they make so that you don't want to be there....
