Can I Offer You A Literacy Program?

I’m working on the till, and a customer comes up with some kids’ lunchboxes.

Customer: “These are on offer: buy one, get one half-price.”

I scan them up, and no offer comes up.

Customer: “I can show you where I found them!”

Sure enough, there’s no offer ticket on the shelf.

Me: “There’s no sign here that says the lunchboxes are on offer.”

Customer: “It’s right there!”

They point at a stand of water bottles at the opposite end of the aisle, a good four or five metres away, which has a ticket clearly stating that the price and offer are for the bottles.

Customer: “See, it says it there. Your signs are so misleading!”
