A study shows that people tend to be more thorough and take more time washing their hands in public washrooms when there is someone standing behind them waiting to use the sink. What the frak is up with that? Do you need someone standing behind you and watching you to wash your hands properly?
Also, we all have one at work - the colleague that doesn't wash their hands after using the loo, who also happens to be the same colleague that offers you candy when you stop by his/her desk. What the frak?
EWW. I wash my hands just as thoroughly on my own. Remember the dry "leprosy" spot above my knuckles? Yeah, still there. I wash my hands waaaaay too much. Germ freak.
And those people who don't wash their hands after loo-usage make me CRINGE. Go shake somebody else's hand, ugh!
