Have you ever witnessed or participated in a barroom brawl?

I’m watching a movie with a limited bar fight. I haven’t been to a bar in years, but I can clearly remember a some very unpleasant incidents. One that sticks out was a very large, drunken female who came back in after having been escorted out once and, for some unfathomable reason, had removed her shirt. The bouncer really earned his pay that night in removing her a second time. He kept losing his grip and having to re-grab her sweaty person. It was dreadful, but I couldn’t look away. She had two kind of heavy friends that added to the scene and we applauded the bouncer when he came back in. That was not too bad as far as brawling, but another time I saw a simple fight escalate within what seemed like seconds with what I thought were uninvolved strangers all just jumping in and swinging. My partner and I just kept dancing through it all, and we had a couple close calls as people swung past or slid by us on the floor. I have no idea now what I was thinking then, or why I didn’t run for cover. I remember he had on a cowboy hat, so maybe I thought that he could handle anything that came at us. I don’t know.
How ‘bout you? I’ve always kind of wanted to be the person who hits people over the head with a bottle as they come staggering over to the bar, but somehow my life never worked that out for me.
Have you ever seen or been involved in something that might make a good scene in a movie while in a bar?
