So, we have locked doors on each floor just outside the elevators, so that, even if you manage to get to the elevators, there are only a limited number of floors you can get to. So, you swipe your badge, and then you open the door and go in. There's a little sign that says something about an alarm going off if the door is left open too long. Well, it happened on Friday, and it just happened now. It's a really annoying high-pitched whine. It's not too bad at first, but it gets really fucking annoying as it goes on and on and on. Stupid fucking people holding the doors for people and shit like that.
