Not my experience, and doesn't really make him as an ass...
A friend of mine was working one of the bigger rides at the Calgary Stampede about 5 years ago. It was the Bungee Chair, which is essentially a large porch swing with seatbelts attached to rubber cables which are in turn attached to 2 poles 150 feet high. You strap in, the chair is released, and you fling around in the sky for a few minutes.
Dany Heatly was in town and had just strapped himself into the chair and my friend tossed a large bolt (from out of sight) onto the platform in front of the riders. Heatly started freaking out and literally tore himself from the ride (the belts/restraint things locked by this point) and flung himself off the platform. Upon seeing my pal laughing his stupid ass off, Heatly walks up, grabs him by the collar and chucks him into the dirt, swears at him a whole lot, and walks off.
I'm surprised he didn't knock his block off.
Heatley was in a horrible car wreck, bear in mind.
A way back when the Senators played at the Civic Centre, the majority of the hockey players would be forced to come through the upstairs portion of the arena to get to their buses. The only players to find a back way out were usually Gretzky, Lemieux and the like.
Anyways, after a Sabre game in Ottawa I was running around getting autographs from the players. I got Rob Ray's autograph and then he kept using my pen/marker to sign more autographs for other kids. Considering I was probably 15 at the time, I was patient enough as he signed autograph after autograph for other fans which basically left me with nothing to get other signatures with. Finally, I went up to him and asked for my pen back and he turned and gave me the worst stare-down I have ever been given in my life. It was scary as all hell and I still remember it exactly as it was to this day.
I can't remember if I ended up getting the pen back or not.
Good on him, I mean why would you wait around for a stinking pen?
The worst thing I've seen from a player personally is when the Allen Cup was held in Lloydminster, AB. Theoren Fleury was playing for the Horse Lake Thunder, and whenever the media interviewed him he declared that all of the success of the tournament was because he was playing in it, and that the fans were ***holes. I sat by the bench for one game, and he told a few fans to go **** themselves at one point in the game.
