I waved the "key" at the lock on the door to "my" room at a JW Marriott. The lock clicked, and I opened the door. I "found" a nude couple on the bed with the woman astride the man. The angle left nothing to the imagination. In the second that it took my brain to register what I was seeing (I had arrived late at night after a long flight), the woman turned and looked at me. She said nothing, and did not stop her motion. I said nothing as I backed out of the door and closed it. My next stop was the front desk. I of course got a different room, a lot of apologies, and extra points. The next morning, I saw the couple at breakfast. The woman saw me, made eye contact, and smiled.
