I understand the convenience of having an elevator, I swear. But why in the world do you need to call the stairwell a fire exit? It's not. It's a fucking stairwell. Stairs were there before shitty elevators came in and ruined everything for everyone. Maybe the fat folks got the better end of the stick, but I digress.
Stairs are stairs. They don't become a fire exit out of nowhere, they aren't transformers. They are a rise and run type of equation; you go up and forward. No more no less, fuck you.
