Why Can't Poker Players Behave?

Read the following, from today's Card Player.com's coverage of the Doyle Brunson North American Classic:

"Tournament Director Jack McClelland just stopped play in the middle of level six for an announcement. After play concluded last night players were treated to a free buffet. Allegedly, a few of the "famous players" were abusive to the buffet staff, and the incident was brought to McClelland's attention. This prompted McClelland to issue a warning: any player who is abusive to buffet staff will be assessed at least a 30-minute penalty. "Behave like ladies and gentlemen," McClelland demanded, "or you can go down the street and pay for dinner."

This raises the question - why can't poker players, especially the famous ones, behave? I had always heard stories about dealers being treated terribly by some of the top professionals, but I guess I naively thought players kept their antics to the poker tables.

Personally, I think if a tournament player is "abusive" to anybody involved in the tournament or the hotel hosting the event, that they should be disqualified from the tournament and blinded off. It is the player's privilege to compete. There is no entitlement that allows players to throw temper tantrums, or act like children.
