While in a restaurant bathroom the other morning, I watched an airline stewardess leave a stall, stand in front of a mirror, fluff her hair and walk out *without washing her hands*.
I announced rather loudly to my audience (Katie) "I guess it's a good thing they don't serve food on airplanes anymore."
It's not pee on your hands that's bad in restrooms...it's all the fecal bacteria that pretty much lurk on all the hard surfaces. Whenever you flush, water from the toilet aerosolizes and pretty much lands on everything. Also, bacteria can move on their own, and often the dirtiest part of the public restroom is the lid to the little garbage can for used maxi pads and tampons.
