Recently I had a few friends come over to play a board game. At one point, one of them went to the bathroom, which was near the area in which we were playing.
After about 5 minutes (which would indicate he was defecating and not just urinating), I heard the toilet flush, and then immediately the door opened and he came out. The fact that the door opened immediately after the flush would indicate that he did not wash his hands.
I'm a person who likes to keep things clean, so I was irked by that. I didn't say anything though, as I was rather dumbfounded. There are actually people who don't wash their hands after defecating? Apparently so.
So what could I say or do next time to try to ensure that everyone washes their hands when they go to the bathroom?
