LOL....my husband had an ADMIN who sat right outside the men's room on a jobsite.....she could hear whether the sink got used....so she'd admonish those (even customers/sales people) who didn't wash their hands to go back and do so. It was hilarious and my husband thought she was great.
I watched a father whisk his young son straight out of the mens room at a local restaurant without stopping at the sink- the boy probably had Norwalk virus, too (judging by certain auditory and olfactory clues I could not fail to notice!). Now there's a kid who is really being taught something, all right. (Bet they went right to the salad bar to fondle all the fruits and vegetables...)
