Weird apartment scenarios?

My apartment building just started locking the laundry room door. We have all been given a key to get into it now.

My question is, what prompted our landlord to keep the door locked at all times? Was someone breaking in to do laundry? Who would do that? It costs $2 per load! Make it make sense.

I know we all have questionable stories from living in apartments. Who has the wildest one?
