"As far as AFTER is concerned unless your aim is terribly off..."
You lack an understanding of basic hygiene.
The aim being off is hardly the issue. Urine is sterile. It's possible
to drink urine without becoming ill (unless the urine is from a
diseased individual). There are even quack health books (at least one)
advocating drinking one's urine as a way to health (There aren't any
Art Bell listeners in the house, are there?).
The reason the hands are washed after urination is this - the groin
area is warm, sweaty, and therefore a major breeding place for germs.
The hands are washed after urination to kill the germs.
Posts like the Grump's which I excerpted above and a few others show
how important it is to be extremely health conscious in public
settings and especially (I believe) in casinos.
