Come on people, I know your Mom taught you to flush! Yes, public restrooms have a high germ factor. But that's what the paper and the toilet seat covers are for. If there aren't any or you just can't bring yourself to sit, please wipe up the seat and the floor, so I don't have to. Go ahead, use all the paper you need. Use it all if you must. I always carry tissues but now I'm considering carrying Clorox wipes and the warehouse-club-size hand sanitizer too.
I'll bet you didn't wash your hands either.
