I had tickets to the Cher concert on Sunday. I was at my seat and standing for the show (it s a live music concert) and the woman behind me kept complaining about me standing. So she got security and they removed us and offered us downgraded seats. I refused the seats they were offering me and asked them to show me in their policies where I must remain seated and they refused. They said if I didn't take their downgraded seats (which was in a box BEHIND the stage) or went back to my seat and remained seated for the whole show then I had to leave. I'm not going to remain seated at a concert that I paid $350 for so I refused to sit down and they ejected me from the arena where I was arrested for trespassing. They never once offered the one miserable woman behind me another seat since she was the only unhappy customer. I contacted their management for a full refund of my tickets and they refused. They said it was my behavior that had me ejected. My behavior? They have cameras, and you can see I'm upset when they are refusing my own seats to me. But I was not physically acting out toward anyone and should have never been removed my seats to begin with. What kind of venue picks and chooses what made up rules to enforce.
