AIRPLANES are the scariest germ labs for me. And I’ve gotten in to the habit of washing my hands before AND after using public restrooms.
Oh man, I agree about airplanes. Disgusting. I hate flying and rarely do it.
If you pee in the sink, you can wash your hands DURING.
Thats is a slightly helpful, but in reality useless exercise.
Think about it. You go to a public restroom. To get in you grab the doorhandle. You then go do your business. Possibly touching another door depending on what you need to do in there. If you did go in there you have to touch the door again to get out. You then touch the faucet to turn on the water. You wash. You touch the faucet again to turn off. You then at a minimum touch the door exiting. Your hands have come into contact with two 'infected' or 'dirty' surfaces post washing hands.
What did washing accomplish?
Just use a liquid hand sanitizer after you exit.
