Well of course there's my "generic universal solution" which has not failed me yet - kick 'em in the nuts.

Or you could try this: have a buddy who's not known to the staff sign up, then keep a low profile in the room. When the line jumpers try to pass 'em up, it's time to throw a friggin' hissy fit. Make sure the big bosses get involved, don't let it get smoothed over by the brush who's letting the local schmuck skip line.
