There's a possible problem with that.
A gaming convention which I attended a few years ago ran into the same problem when people kept leaving the door to the foyer open, letting lots of cold air in and freezing the people who were doing registration. They put up a sign saying "Shut the door. Every time you don't, a pixie gets set on fire (Trogdor style)."
After they'd remembered the sort of people they were dealing with, the registration people amended the sign by crossing out the "n't". :d:
