Good Grief!
Why do they have sinks in public restrooms in the first place? I presume it's for people to wash their hands. And what have these people likely been doing prior to washing their hands?
So why is brushing teeth in a public restroom considered disgusting, and hand washing is not?
Is not the purpose of hand washing to remove potential debris from that previous unmentionable activity? And wouldn't any such residual debris then go into the sink?
