Crappy Finger Painting

I was talking to my pharmacist friend at work the other night and he told me this story.
Years ago when he worked at a different store, one day there was a boy around 12-13 who asked to use the bathroom. He led to the kid to the bathroom, but after being in there 20 minutes or so he knocked on the door and asked if everything was ok. The kid said yeah and he would be out in the minute.
The kid comes out of  the bathroom and my pharmacist friend goes in to find that the kid had been doodling. Finger painting scribbles covered the bathroom wall, with shit.
The kid had been finger painting with his own shit, in a drug store bathroom...
My pharmacist friend went and found the mother and said "hey I'd like to show you something" and brought her and her son to the bathroom. The mother asked the kid if he had done it and he admitted. She slapped him and told him not only would he be cleaning up his mess, he would also be cleaning the entire bathroom until it was spotless.
Unlike in Potty Time I applaud that mother.
