It would have done no good, the manager would have backed the doorman to to hilt.
A few years ago I was sat in another bar will my wife, only went in for one but it was happy hour and ended up having 10 Buds. the barmaid ID everybody, each time they ordered a drink. They was only maybe 10 in the bar and she know them all, but still ID them every time they came to the bar. I asked her why she was doing it. She told me that it was the law and if the police came in and found anybody under 21 in the bar, the bar would be closed down straight away with no excuses.
