I Adore A Door

Today's post is from the ever-prolific field correspondent, Shu.  As always, click the picture to enbiggen.

This was at a hotel where I stayed a short while back.  I figure there are three possibilities:
     1) Deliberate mischief;
     2) Last person to use the door can't read;
     3) Someone put the sign on the wrong door.
For good or bad, as many times as I walked past the door, I didn't witness any door-related calamities.
