Well I can tell you the worst.
I was at a U2 concert in Dallas Texas. U2 was going strong by then. I was standing on a chair clapping like all the other people there. Someone tried to pull me back off the chair. My arm swung behind me. A bouncer saw it and thought I was trying to hit someone. He grabbed my throat with both hands and pulled me off the chair by my neck. He was at least a foot taller than me. He asked to see my ticket. He tore it up and threw it into a crowd (so I had no ticket stub). He escorted me out a side door and two other security guards threw me into the parking lot. With all this rough treatment I pissed my pants to top off the evening. I hate Texas.
