I stumbled upon this photo recently on a blog I visited.  The photo was taken in Nürnberg, Germany and the author writes the following:

I was staying at a small and inexpensive hotel near the city center. I returned last night around 11pm. I was really tired from the long day, and with a heavy notebook back with me. I was going to enter the elevator to the upper floors, when I saw this signage on the elevator door.  So there I was standing in front of that door, about to press the button, still thinking about the consequences. Not a good sign. Can I take the risk? What would you do?

Well, what would you do?
