Elevators

Today I got stuck in an elevator. The doors closed and it took me to floor 13 where it stopped and refused to open the doors again, which surprsied me because:

a) I hit the button for 16, and
b) There was no 13th floor

In any case, it was pretty simple to get out considering that both the elevator “call-the-front-desk” button and my cell phone were working. It was just an odd experience.
