I know this is an oldish thread, but cash handling is a pet hobby horse of mine.
Seems cash handling in the US is as sloppy as it is here in Australia.
The only place I see good cash handling these days is in the bank.
I think it is possible that lots of people including "cash handling experts" have never seen a good slight of hand operator work.
I have some friends who are professional close up magicians. To anybody with even basic skills of prestidigitation, palming a substituting coins and notes is trivial.
These guys, you could place 3 coins in their hand, they could appear to close their hand and open it again, and there would be 4 or 2 or 3 different coins.
Slight of hand, like most stage magic skills has its origin in crime and fraud.
So good solid cash handling has the money presented in clear open view away from hands.
One person lays the money down, both keep hands away till the cash is clearly seen, the other then picks up.
This is why the bench we serve customers at is called a "counter".
An entirely civilised item, there should be more of them.......I nice block of wood for presenting cash properly.
Bravo
