I checked in a hotel once. Sat down at the little desk area to chill before I had to hop right back up to attend a meeting. I heard the door rattle, and then backs in one of my coworkers pulling her luggage in the room. When she saw me, she was so embarrassed, and exited the room much faster than she entered. We still joke about that to this day. I now use the hotel door latch as well as much stranger things could happen.
