Some people have more than enough time to play with their toys.
Where I work, the restroom lights are hooked up to some kind of motion detector. No movement for half an hour and the lights go off. On two occasions I've gone entered to find that the lights were off. I figure I'm the only one there, but then I hear someone start to work the tp dispenser in one of the stalls.
Now I don't mind relaxing while sitting on the can, but over half an hour!?! Maybe he fell asleep, but I think the more important question is - how long would he have sat in the dark?
