Someone who works behind the bar doing everything but serving drink(unless of course the bartender is incapable and said greyshirt rescues bartender from the weeds). They do things like restocking the fridge, replacing spirit, wine, and juice bottles, fresh squeeze, glassware, plastic, mixes, ice, et cetera. Sometimes called upon to bounce due to lack of redshirt balls or brains (not including Nick or George). Often found having a good time and responsible for the "smooth" running operation of the establishment. *Not to be confused with Amigo's*
Paul 6-Stack down beach stairs, true greyshirt.
In other words anyone but A-team.
