A well known store full of freezers.
Customer: "How much are the grapes?"
Checkout: "They're two for £3 or £1.87 each"
Customer: "But I have two items?"
Checkout: "The grapes are two for £3"
Customer: "Yes, that's right, two for three pounds."
Me: [With only an hour for lunch] The grapes are three pound if you buy two punnet's of them, it's not £3 for any old two items in the store!"
How do I find these people? Is it just me?
