Food for thought - when one gets done doing his/her business, one of the first thing they touch is the faucets. Then they wash their hands and guess what, they touch the same faucets to turn them off. What's worse - what you sullied your hands with or getting a strangers cooties?
I guess there's something to say about the no-touch sinks and toilets flushers...But, then there's the handles to dispense the paper towels....
