Reason For the New Rule
When supermarkets entered India, they would give a printed-out receipt and the security guy at the exit would check your receipt and eyeball the groceries…to prevent shoplifting. But here’s how we cheated the system.
You would drop off the groceries at home, hand over the receipt to someone else, and that someone else would enter the supermarket again, buy the exact same stuff and walk out without paying. They would show the receipt and drop off the groceries at home, then hand over the receipt to someone else…etc.
The people who figured this out tried to keep it a secret, but word got out, and the supermarkets handed the security guy a rubber stamp that said “delivered” or “exited,” and made them stamp every receipt.
