So she made a killer martini and was a bouncer? Who knew?
She told the bouncer who the potential trouble-makers were. People disrespectful of others are more likely to pick fights. Those could include people wielding extreme opinions and failing to modulate those views, using inordinate amounts of profanity including ethnic and sexual smears, and people making hostile gestures. Trouble tends to escalate and not appear suddenly. The ideal is that a bouncer bounces someone before someone throws a punch or disabuses someone of a perception of hostility. The perception of a bold out of the blue is almost always the result of inattention.
