I have noticed here of late that Sam’s doesn’t check people to see their cards when I go there.........................
They still check people at Costco here, as they enter and then check receipts as they leave.
However, many stores here are shutting down self-checkout registers because of theft. Customers don't scan all the goods from their carts, and underpay. Stores had let go checkers in favor of automated self-checkout, now reversing policy but in the meantime half the manned checkout lanes are closed due to fewer workers.
