I recall last year, when I was working as Arisia Security, having to rather forcefully insist that someone leave the nice Skank party people alone. He kept insisting that he met the "dress code" but he was rather offensive both in manner and odor.

I completely respect the desire to keep skeevy people away, and make everyone else comfortable. It's a hard thing to do, even when you have the help of the party czar and con security.
