I used to work in a bar, it was very respectable and smart with a restaurant attached so popular with diners. Anyhow, one night I declined to serve a man who had had way too much to drink and was making far too much noise. And I was in charge of the bar that night, so it was my perogative. Besides, I was thinking of myself, as serving intoxicated people is actually not allowed. I did this very politely, though, and explained why. And said he was welcome to come back another time.
This man didn't really say much, but then another girl who was actually his daughter, suddenly popped up and lost the plot entirely.She started shouting and swearing, throwing ash trays at me and the friend i was working with and then proceeded to try to attack us with pool cues. Also, pulled out some of my friends hair. And she hadn't even been drinking! We had to call the police - she was arrested and had to go to court. Sometimes the customers just aren't right after all!!
