Yeah, I usually leave toilets cleaner than when I find them as well, 'cos I do the initial clean up that's required before I go anywhere near it, and I certainly don't leave any mess myself.

Toilets in nightclubs or the casino can be downright frightening at times. I went to an S&M club once, however, and the toilet there was spotless.
Actually, it just occured to me that there might be a reason it was so spotless .... oh ick.
