I was told this story from my wife and it was told to her by a CA she flew with a while back. Not sure I believe it completely but still funny.
The CA in question gets to the hotel and goes to the desk with urgent business to take care of (#2, duece, drop the kids off, etc.). Anyway, he hurriedly grabs the key at the front desk, enters his room, and goes immediately to the bathroom and manages to make the seat at the appropriate moment. As he is relieving himself, he realizes that someone elses personal items are laid out in the bathroom. The guy didn't miss a beat. He finished up his business, puts himself back together, exited the room, and goes back to the front desk to get a new room. The CA to this day is not sure if the other person was actually in the room at the time of his intrusion.
