Getting someone fired from their job?

I have a dilemma. I'm debating whether I should report someone's behavior which could potentially get them fired.

Part of me says to walk away. The other half of me says I shouldn't let them get away with unprofessional behavior.

Overview: I'd hang out at this spot with my friends and one of the workers would flirt with me. I would flirt with her but she was kinda sketchy (one time single, the next boyfriend). I didn't take her seriously so I backed off with the flirting. She would get upset if other women would talk to me. One night she got very mad with me because I was flirting with a group of women. She was out of line and I left. I was so upset with what she did, I went back and I spoke to her. We smoothed things over.

I start going back in with my friends and everything was fine. I'm there one night and am talking to these women. Having a nice time when a man came up to me and started talking trash. It seems the girl who works there sent him up to me to start a fight. Nothing happened but the guy was a jerk and it could have been an ugly situation.

The girl denied having any involvement. She was lying as the jerk gave her up. I found out he wasn't her boyfriend but a guy who is very into her. She used him to hopefully get us to fight.

I spoke to management and they tried to cover it up. Nothing was ever resolved. Some of my friends told me to let it go. Others have told me to post what happened on the internet and write a letter to the owner of the business.

Just wondering what others think?
