I don't know whether you've noticed, but staff on the Tesco check-out are required to wear large badges which tell you when they joined the company and some interesting fact about themselves. This might be that they like football, for instance, or enjoy gardening.
Yesterday, as I packed up my family shop, I read that the lady on the till spoke French. This didn't strike me as hugely surprising, as she had a French name. My first instinct was that English would be more useful in the outer reaches of south-west London, but I've been reflecting. Most of the customers at my local store probably buy the Finest range, where the items are prepared au jus or à gratin.
"Sebastian! Run down to the lady at the check-out, there's a good boy. Ask her if the bouillon in the bisque is vegetarian, would you?"
