Aim to the bathroom on the left and whatever you do....don't look to the right. Only time you're screwed is when you get an ambitious one (probably a newbie) who comes out from the safety zone of the podium and comes after you....then it becomes a running game. Duck in the bathroom and they usually don't follow you.

Last resort....remember the hari krishna's in the original Airport movie?? Just start punching the crap out of them and leave them in a pile in the middle of the concourse.
