When I was still trying to use self checkout I put cash in to pay...it took the cash but I didn’t notice it was not deducting the cash as it took it. When I realized I got an employee to come help and told her what happened. She acted like I was a scammer deluxe. I told her I knew they had to have it on video and she needed to get the manager ASAP. I was about to truly unleash on her because of her attitude and because she didn’t suggest someone needed to look at video before I brought it up. It seemed it was fine with her if I got scammed.
I did get that sorted out but I was glad they had tapes to look at. Another day I gave the cashier a $50 and she swore I gave her a $20. Video kept me from getting scammed again.
On your last bit. I always make it a habit to say to the cashier what I am giving him/her.
Especially if it’s more than double the sale amount.
For instance, if I spent $7.00 and give him/her a $20 bill I always say, “Out of twenty,” so they look and see it’s NOT a ten.
Personal rule...
If I pay with a hundred or fifty, I memorize the last for digits of the bills serial number. Any problems with change,I politely ask to speak with a manager and recite the number. Solved!
In most big box stores now the store management can not look at or delete videos. Only the corporate security department can. This is partly to make it harder for local managers to be in on scams.
