What did you do or say that got you kicked out of a place?

Stepped in between two people that were fighting and one wouldn't stop so I ended up showing them they weren't so big that they couldn't be taken down. I didn't get arrested because the guy attacked me when I was trying to stop him and his girlfriend (?) From battering each other, but the officer told me to never do that again and asked me to leave the property. I don't regret stepping in because he was laying her out. They both got arrested.
