Here is a nice one...
I took my niece to an aquarium today while on vacation and the exterior door handle pulled up but no action inside the door to open it. She had to crawl across and open it from the inside. I don't even have any tools here with me to try to take the door cover off and look to see what might have come loose or broken or fallen off or whatever... The interior door handle still operates normally and the locks work fine. It's odd.
