Receiveing Change

A long running pet peeve, cashiers who pile coins on top of bills prior to handing over change due. The resulting precariously balanced pile requires careful handling. I wonder if I'm the only one who finds this annoying? Most cashiers who do this don't even realize it's an annoyance. But, did the cash register hand it to them that way. No. They created this state of entropy. It's much easier to receive coins in a open hand and then the bills. That way, I can place the coins in my pocket, coint purse etc and the bills in my wallet.
