I do the same as Sue-paper towel first to turn on the water, cover my hands in soap before using said water, then paper towel to shut it off and another to dry. With those dispensers with the handle, I get a towel ready and hanging first-of course, some really dumb women think I've done that for them, which means I have to start all over- 'uh, you saw me get the towel ready, why are YOU taking it and using it?'
I also carry anti-bacterial hand cream in my purse and waterless wash in both cars.
Working with kids for 3 years, I was sick from October to June each year, including two flus and pneumonia. Overkill? maybe.
I will say though, that study should have checked the booths in ladies' rooms. Women ARE slobs.Many cover the seats in pee and don't clean it up, they don't flush, they toss unwrapped used 'hygiene products' in the little pails provided....A booth in a ladies' room is like "Let's Make a Deal". You never know what's behind those doors.
