OK, I’ve thought of another one. Definitely infuriating beyond proportion for me.
When I go to the cash register and the charge is (let’s say) 8.17 and I hand the cashier a $10 and the change is handed back to me as a “receipt sandwich”:
coins
receipt
bills
Yeesh! I hate that! I have to confess I actually lose my temper and act like a jerk, it’s such a STUPID way to give someone their change. I slam down my grocery bags and my wallet, take what has been handed to me in BOTH hands, SLAM the coins down on the counter or belt, peel the receipt away and toss IT down, pick up wallet, insert bils, pick up coins, put in pocket, pick up wallet and groceries and glare. Clueless cashier looks back at me going Wha?
PEOPLE. Wake the fuck up. That is totally not how you give someone their change. In fact, of all the way to do it wrong, that’s the wrongest.
Here’s the classic right way: "Eight seventeen out of ten, eighteen, nineteen, twenty, twenty-five, fifty, seventy-five, nine, [has been returning coins FIRST, obviously, smallest change first], ten [bill ABOVE the change], thank you [hands receipt]. It all goes into the receiving hand. Coins end up in the hollow part of the palm of the hand. Bills lay above it where they are easily snagged by the fingers and separated from the coins, one-handed, for easy insertion into the wallet. Receipt on top easily separated from the rest for discarding or pocketing separately. (No one I know puts the receipts in with the bills).
But OK that arose in the day when cash registers didn’t TELL the cashier what the change amt was. I have no problem with this alternative, more modern way: "Your change comes to one dollar and eighty four cents, here’s one [dollar goes first] and eighty four [coins] and here’s your receipt. Bill goes into palm, snagged between two fingers for easy independent handling; coins on top of bills is fine, receipt comes after and is snagged between different fingers. A quick tilt and the coins slide free and into the change pocket, the bills (trapped between index and middle finger perhaps) into wallet, and the receipt (perhaps between thumb and forefinger) kept separate for tossing out or dealing with separately.
Its that “receipt sandwich” thing that just makes me nuts. There’s no way to deal with that mess one-handed.
