The photo below shows a frequent occurrence in my office bathroom.
The mess below the trashcan isn't from lazy people - well, that's not true. The mess wasn't created by the people who use the restroom. It was created by the lazy asshole who puts the paper towels in the dispenser backwards every other day. When installed upside down they don't pull correctly and you end up just ripping the towels into little shreds. Eventually you just put your hand up the little slot and pull out a stack to put on the counter as a temporary fix.
This picture was taken after they had cleaned up the little shreds of paper twice that day. Not once did the maintenance staff think to use their key to open the bin and flip the paper towels over. They just kept coming in and cleaning it up. Brilliant.
I really wonder if the guy who screws this up each night knows he's doing it wrong. I wonder that because some days it's correct and other days it's not - it's random.
Is there some kind of training the guy can get? Maybe a short tutorial on how to place paper towels in the dispenser that comes with a certificate of completion that he can put up on the wall in his little janitor closet.
I know it's just paper towels, but it's not something that should be done wrong. It's too easy not to screw up.
