Public restrooms

I have been thinking about the evolution of bathroom sanitation lately. As a nursing student, I learned how to wash hands and try to keep them clean etc. It made me think back to when I was a kid. I remember going into some restrooms in places like gas stations and there would actually be a machine that held a round cloth that you would use to dry your hands (or not yuck!). And then it went to the paper towels in the machines, that you either grab too many or not enough and have to fight the machines for what you get, to the new things that I love so much, the hand dryers. My kids really enjoy them too and as long as you hit them with the back of your hand, it is very sanitary I think.
