My latest evidence for this is to be found in my local supermarket. The tomato is a fruit, botanically speaking. Don’t believe me? Then check it out for yourself. Yesterday, I bought some tomatoes and at the check-out proffered a voucher which would reward me with 25 pence off the price. Unfortunately, the computer wouldn’t allow it. There’s no point in arguing with the check-out person in such a situation, because they can’t exercise any discretion at all. After all, they’re not going to be able to do it for tomatoes if they can’t do it in the case of a manifest absurdity:
