^^^^^^ This. Not trying to talk everyone into it, but politeness respect and some light-hearted banter with fellow DL employees seems to set one up well for boarding at a sensible moment, at least while in uniform. I'm always prepared for a "step aside until your zone is called" reaction, but it's never happened.
