Yeah right. Sorry, I don't buy it. I've had the sad misfortune of having to use the facilities in Penn station, and I can tell your there's no way I am touching anything someone else just put their mitts on after doing the deed. Consider this:

A man comes in and uses the latrine, he then grabs the water knob and turns the water on, contaminating the knob, he then pumps the soap dispenser with his other hand, contaminating the soap dispenser. Then he scrubs his hands under the water. Then he turns the water off, re-contaminating his hands. Then he grabs the paper dispenser lever to feed paper towel out, contaminating the paper dispenser lever. The next person to use the latrine and the same sink will cross contaminate himself and the things he handles to wash up. That ain't gonna be me folks.

If the faucet and the soap dispenser and the towel dispenser are those new sensor driven units, where you wave your hand and the water turns on, the soap squirts out, and the towel feeds automatically, then I wash up. Otherwise forget it. Since they don't bother to even address the issue of cross contamination sources due to manual manipulation, then they only tell half the story.

I treat public bathrooms no different than the subway. If you touch any surface with bare skin, you should consider it contaminated and in need of a good cleansing in a controlled environment.
