Nope never been kicked out, but came close once, when a waitress got pissed at me, thankfully one of the dancers came to my defense and told the bouncer that the waitress was an idiot, although he did get a bit rude with afterward and watched me like a hawk and was a real asshole for a few weeks.
I have seen people kicked out many times, and most times the people deserved it. There are two I remember most. The first was at Tattletales in Atlanta about 15 years ago, one guy was drunk and rude and started grabbing dancers on the floor. He got a bit mouthy and got his face shoved hard onto the table by two or three bouncers and then shoved out the door.
New Orleans about 20 years ago, was the most brutal, I ever saw, and it looked like they guys did nothing to deserve it. I was about midway in my tour of the the many dives on Bourbon street. There were so many dives I am not even sure which one it was, but it was very seedy even for the ones on Bourbon Street. I was there about twenty minutes at most and one guy stood up and tipped the girl, and I think just lightly touched her leg, and immediately three bouncers swarmed on him and the other guy he was with. The manager comes up and started yelling at both customers really loudly and told the two to leave.
The next thing I knew one of the the bouncers punched the guy standing up in the face and the guy sitting down was knocked down in the chair on his back. A few more bouncers showed up and threw both of the them forcefully on the street, and it looked like a few of the bouncers started kicking one of the guys outside.
I asked the stripper who was sitting next to me, if the bouncers can get away with that, and she said, "yep, happens all the time." That was enough for me at that place, and I quickly left the club.
