On my last trip the hotel was very nice. The door to the room was a heavy steel door that opened in to the room.
Notice the funny thing at the top of the door.
This is a close up. You can see it has a rubber wheel. The door open in so it can't stop the door from going out, the door frame does that.
I know they did not put that thing there just to puzzle me, but that is the best use I can see for it now.
What the heck is the real purpose of that thing?
