Just a short story from a convenience store in the sunny UK.
A sunburnt lady wished to purchase a lovely fruity ice lolly, but she did not wish to pay the £1.25 that this item costs. Angrily, she jabs her finger at the wrapper where it says "only 99 calories!", slams down a pound coin on the counter with a smug grunt of "99p."
In fairness, we do handle a lot of price-marked stock, so I'm very understanding with my explanation - "I'm sorry, but that's actually the calorie content. The price is £1.25"
She picks up the ice lolly and examines it as if I had just told her that it came from space and contains unicorn tears. "But it says 99p..." She says, genuinely baffled.
I'm thinking to myself "Please laugh. Please realise your mistake. We can laugh about it together..." but of course not...
She gets even more red faced then comes out with the old favourite "Well that's misleading" and pays the full price with a huff.
