“Oh sorry, sir. Now that I realize that you are present, standing before this desk (and wearing a suit), of course we have many available rooms for you. Pardon my error. If only you had used this sort of unassailable logic when you first attempted to check in, we would have been able to produce a room for you immediately! In the future, always point out to hotel desk clerks that you are standing right in front of them, wearing a suit. That will guarantee you get you a room, whether there is a reservation for you or not!”
