Asked to leave a concert while sitting in my seat watching the show. Apparently the confrontation between the two people sitting to my right which I didn't even know or come with made me guilty by association. Absolutely unacceptable to be removed from a show with no explination or reason. I've been to a ton of concerts and never had as much as a warning. I will not step foot in that casino again and will be sure to let all my friends know not to attend concerts there as Well. Also they asked that you not stand up during the show. Pretty sure it's a concert not a movie theatre.
