I wanted to bring attention to stairwells in keyfob-entry apartments.

I got locked in a stairwell that needed a keyfob to exit but not to enter (when leaving building), and the door locked behind me. Only took the stairs because the elevator needed the fob to head back down to the lobby.

Thankfully someone was walking by to let me out, but man that shit had me panicking for a good 5 minutes.

Be careful everyone, always make sure you can get back out of the doors you go through!
