On a similar topic, I've always been surprised that people wash their hands after using the toilet in a public place, only then to touch the door handle with their hand.
I always use my sleeve to open the door after washing my hands. Obviously it's a dirty sleeve put it's better than my hand touching it after hundreds of people have used their handle with their hands after handling their knobs.
Probably a futile act as naturally you would end up touching other surfaces later but still, it still seems odd to wash your hands then touch a pissy door handle.
