That's a great story 88fingerslewy, and I had a similar encounter.
I'm at the Sports book in Vegas with a bunch of friends and were watching like four games at once on the big screen. This fairly healthy looking guy in a wheel chair pulls up against the wall and is watching too (Fairly healthy in that he really don't look like he needs to be in a wheel chair, but no one asked). Anyhow, this other guy (50-ish) comes along and sits on this small end table, blocking the wheel chair guys view. The wheel chair guy pulls up along side of him in the isle and asked him to move. The guys tells him, 'no'. So they start about a 5-10min long exchange of F'-U's, and I think the guy rammed him a few times with the wheel chair and the guy still sitting on the table took a couple swipes at the wheel chair guy with a rolled up betting form magazine. The arguement was also about the wheel chair guy using that end table to sit his ash tray. They go on and on and our group is listening in and laughing our asses off. Several times someone stated, 'this is more entertaining then the games' ... well, the guy on the table still wouldn't move, so the wheel chair guy positioned his still lit cigarette butt under the guys ass on the table, then rolled back and watched it burn the guys ass. The wheel chair guy never even glanced over at us where we were practically rolling on the floor laughing. He then strolled away and the guy felt his ass on fire and patted it out.
Ahhhh ... remember when the games were entertaining and the side shit use to be an unwanted distraction?
