Ok, forget public bathrooms. I have an even more fundamental problem wtih people who don't keep their personal bathrooms clean. Yes i'm back to this because it's the kind of thing that causes divorces. All that alleged love WILL die when you discover their horrendous bathroom manners. Why do you think there are couples walking around angry with each other for no reason?
Have you ever walked into a bathroom in a respectble place - office, household, establishment, whatever - where seemingly respectable people are supposed to live and work... and then you walk into their disastrous bathroom and think, what the... wait a minute!!
Then you look at the people and now in the back of your head you're like, so you, upon your tie and big english... still? Yes, obviously i take this bathroom thing very personally, but i think i'm finally done. It's not rocket science. It's just basic courtesy, right?
"Do unto the bathroom what you would have other people do unto it beforeyou get there". Or maybe it's not so simple.
