Any LP system will have false positive and false negative. If we can have a perfect LP system without false signals, I think self-checkout systems would have been more wide spread by now.

I was accused of not paying for certain items at a grocery store recently, and I explained that I bought those at another store. The LP person didn’t even ask to check the receipt from the other store. I proceeded with packing my groceries and went home.

I wonder if we can recognize that store people would want to reconfirm if we have correctly paid for the things we thought we bought, and we just answer them. No need to assume ill intent.
