While you're on the subject Zep ever notice many public bathrooms require you to open the door when you're exiting? So just think once you make contact with the handle you make contact with every guy that used the restroom and of course the lazy ones that don't wash their hands.
Most places are pretty good about putting a hand sanitizer dispenser in their bathrooms now so what I do is get a load of that in my left hand and open the door with my right.
