Sainsbury's has introduced a new rule in some of its stores which many shoppers aren't happy about.
In some cases, you'll need to scan your receipt at the self-checkouts before you can leave as a way to provide proof of purchase. Shoppers won't be able to leave until they do this, which has sparked fury on social media.
Many people are frustrated at this new rule, saying they "never" get receipts when they pay for their shopping via self-checkout. Some have even said they'll now be boycotting the supermarket as a form of protest.
