This used to happen to me
Around 10 years ago after a stint on the dole i used to work in an all night garage. This was frequented after 12pm by the usual drunken stumblebums and normally it was all fine. However the garage was in a less than salubrious neighbourhood and around once a week you'd get the local bad boys trying out their freshly stolen credit cards or the scallys who thought it was fun to knock all the pumps off the stands etc and they would get worked up when i refused to serve them.

They were always very cocky, gentlemen who would regularly offer to meet me after work when i wasn't locked in and give me a good hiding. They usually pointed out that i was only standing up for myself because i was behind a grotty peice of glass. I would calmly inform them that they were also behind the glass and that i finished work at 8am. This happened around once every two weeks and not once did anyone turn up in the morning to exchange views.
