Whats worse is when they put it on top of the bills and hand it all back to you at once, like some kind of fucked up magic trick. The shit that I just bought is in my other hand, how in the fuck am I supposed to get this change into my pocket?
Either put both the coins and bills in your pocket together and sort it out later, or don't pick your items up off the counter until you sort out your change.
Because even if they gave your paper bills back separate from the coins, if your other hand is so occupied with the items you purchased, how were you going to get the bills in your wallet anyway?
