The man was a jerk, and the girl not much better for failing to stick up for you.
It happens.
It also happens that, in some cases, the girl accuses the first man of being rude to her, and the second man threatens to teach the first man a lesson.
Then the girl says something like "Settle our bar tabs instead and then get the hell out".
Sometimes people work together to cadge free drinks and screw over a stranger.
