Knock on a random door

You think over the situation you're in. Locked out of your hotel room naked. What a nightmare! Hmmm...nightmare. Maybe you'll wake up soon. Yeah, that must be it, and what wakes you up faster than a shock to the system?
You resolve to do the dumbest possible thing in your situation. You walk up to a random hotel room door and, after steeling your nerves, knock.
