I'm a having a fairly high number of HOW IN THE HOLY HELL DID YOU type of moments lately.
Cashier today rang up somebody for about $96 in stuff, the customer decided to keep shopping to get their $10 gas card when they hit $100, so the cashier prints out the partial receipt so she's got the transaction number handy to pull it back up when they return....
And then scans all of the next customer's stuff on the ticket. They snagged around $160 in product, paid for the other $96 plus taxes, and nobody freaking noticed.
It was only when the cashier was unable to pull up the "on hold" transaction that a cashier manager figured out what she did wrong and ran it up to the office.
I got it all figured out, returned $102.05 to the card that they used to pay for it. Thank goodness they used a card or else I'd be waiting for an angry phone call. I'm still expecting an angry phone call but at least I say we already took care of it.
Then again, when you don't notice your ticket is 75% higher than it should be... well... I'm guessing they're not going to notice the over-charge OR the credit to their account.
Place your bets. :)
