I wash my hands at a public john like at a Trader’s Joe’s store, dry ‘em, and then touch the door handle to open the door. Great, job well done!
That's what the trash cans set up near the bathroom door are for, in those facilities where one can utilize paper towels of some sort. Use one of those to open the door, prop it open with one foot if need be, long enough to exit.
Use your own pen to write with. Little things can add up. The less contact the better. More hand washing can be a good thing. But who stocked those large (paper) coffee cups, or last touched the dispenser handle? (think-- truck stops. Might one find some well traveled little germs in one of those places?)
wrong things are bad?
