I think I'm going to publicly expose a guy who didn't flush the toilet after he was done.
Why do you want to expose him?
I want to humiliate the shit out of him.
Are you sure this wasn't an honest mistake? They might have just forgot to flush. And, even if they did it on purpose, making someone feel bad about their behavior is not a good way to get them to change.
FUCK you, the guy didn't flush a week ago either. Some people are so fucking stupid for trying to stick up for inconsiderate people.
I don't think there is any need to be this upset about this. Perhaps you should just put up a sign telling everyone to make sure they flush the toilet.
