It would be kind of neat if elevators were called "mustards" instead. That way if I were running to catch it, I could yell out: "Can you please hold the mustard?" It would be a funny, yet awkward moment, especially if there were actually a guy making sandwiches IN the elevator. In that case, though, I'd ask for EXTRA mustard, since I really do love mustard! But that would probably just confuse EVERYONE, so I guess I'll just stick to taking the stairs.
