Walmart near me has started using receipt checkers lately and they don’t even really do their job, it’s kind of a gimmick really. They just look at the receipt for a second Don’t even look at your cart, but they stop you every time. It’s just such a waste of my time when I’m in a hurry. I had one person even tell me that it was required by law. No it’s not! There’s no law in the USA that says they have to check your receipt.
A lot of the time they just peek into the bag for like two seconds and look at the receipt and wave you off. What’s the point? If you’re THAT concerned with what’s in the bag, you know it would take much longer than seconds. The entryway would just be a TSA-like checkpoint, but with your purchases. You’ll almost never get out in a timely manner.
