In the UK, almost every wash room has those nail brushes to thoroughly clean your nails and hands. Seems like a pretty good idea actually.
Also, in the UK, it seems the club bars have quit using the common 'chips/nut' bowls at each table or at the bar because of sanitary concerns, ie, every one sticking their fingers in the bowl, something akin to the Seinfeld 'double dip of the chip'
