I was stuck in an office building elevator between floors in FL one night (the only building key work issued was to the elevator from the underground garage, so stairs were not an option after hours). I was able to pull the door open and climb out, but I pulled the emergency stop button so it wouldn't restart on me.There was a terrible accident in the McCormick building of state offices when i was there around 1992. During rush hour in the am the elevator stuck halfway between the lobby floor and the next level. A guy tried to climb out and the elevator dropped severing his legs killing him. Tons of people were in the lobby. I walked through when they were cleaning up. I've never held a limb in a closing elevator since.
The elevator repair guy told me "good move" the next day when I saw him, and mentioned some building codes require that a stuck elevator between floors lock the doors so they cannot be pried open to discourage self help (ok, so those were not his exact words).
