My friend posted his question here too. I was at the same place another time and -to be honest- was a little lit up. I started to get kinda rowdy and the bouncer guy came over and told me to settle down. I did but then he came over after and said I had to leave. I got in a little argument because he was making me leave when I had just bought a damn $10 drink. IN the end they called cops and dragged me outside. Cops charged me with traspassing and resisting him. I think this is total BS because I was only staying for a minute to finish my drink.
Depending on the county this is in and the DA (as well as your criminal record), it is possible to get it dismissed. The restaurant may not even to come to court and move forward with the trespassing charge. As for the resisting charge, these are a little more difficult, but sometimes a talk to the officer about what happened can get those charges dropped as well, especially if the trespassing charge is dropped, too.
