My favorite are the dudes that wash their hands vigorously after using the facilities, then open the door to get out of the bathroom with their bare hands.
Do they think the guys that DON'T wash up use a towel over the handle to get out? lol
Opening the door with a paper towel is just based on goofy superstition. It makes you look like you suffer from a mental disorder. Public restrooms are relatively clean. WTF, you think that as soon as those same people walk out of the bathroom their hands are suddenly clean? Do you go find a paper towel before you open the door to get into your bank? How about to use the drinking fountain? How about to get into your local McDonalds or Subway? The exact same people who don't wash their hands before they leave the bathroom, walk through nearly every other door you walk through. They use the public drinking fountains. They pay for items with money that is then given to you in change. It sucks that they don't wash their hands, but going out of your way to try to avoid their germs is useless and just makes you look like a pansy-ass.
I remember reading a study that showed that the average office phone has about 25,000 bacteria per square inch, and the average keyboard over 3,000 bacteria per square inch, while the average toilet seat has 47 bacteria per square inch. Do you grab a paper towel to pick up the phone? Seriously, public restrooms are bleached on a regular, usually daily, basis. When was the last time the phone at your work was sprayed with bleach? How about your keyboard, mouse or desktop? How often do you bleach your steering wheel? For that matter, how often do you eat hamburgers in the car? Steering wheel, burger, mouth, wheel, fries, mouth, wheel, burger, mouth, wheel, fries, etc.
Life is too short to worry about unimportant/inevitable unpleasantries.
