It's plausible, I guess, for the next of kin to return to the hospital and not know that their loved one's been moved to another unit. I can even accept that a hospital's information system might temporarily be down (evil, evil technology!). What I can't imagine is a hospital visitor, being directed to the fifth floor, asking "are the elevators working?" It's kind of a given. Darin's stupid, unnecessary question gets the slit-eyed, mock-polite, passive-aggressive reply it so richly deserves.
