Nancy (Bartender) asking for I.D.
As far as I know, the U.S. is THE ONLY PLACE IN THE WORLD where legal drinking age is 21, the rest of the world is usually 18, I'm sure that includes Bahamas, why would she bother with the joke and why would they fall in it??? Cuz these guys are more than 18, easily 20.
