My office is now sharing our restroom with our new neighbors who have joined us on the same floor. Suddenly, we are having restroom conspiracies. Not in the sense of poop, but in the sense of urination all over the toilet bowl by nasty women who splatter everywhere and do not clean after themselves. We know it's our neighbors because we never had problems like this before they moved in with us.

I am trying to make a sign to put in the bathroom to kindly request that people clean up after themselves. My question is this: do you know of a smart but non-offensive sign/quote that we can put up in the office to remind people of bathroom etiquette?

Please help... thank you tons...
