Bathroom security -- huh?

I went for my platelet donation the other day at the Red Cross. Before I got hooked up for a couple of hours, I decided that I should, um, use the facilities. There was a sign at the receptionist that said to use the bathroom in the hallway. OK. "...and the code is 5421." HUH?
The bathroom had a Cipher lock on the bathroom door! Has it really come to this? Are people stealing toilet paper now?! Is the economy THAT bad?

I think I'll ask about what lead to that next time I'm there...
