This morning, I was in Tesco at 7.05 am. Not my usual time for supermarket shopping, but I needed bread, as well as some cash for a guy who was delivering flooring to Woodford Towers for our new kitchen.
In front of me at the checkout was a man with four tins of tuna, three tins of sardines and two tins of pilchards. Nothing else.
He asked to pay for the sardines and pilchards separately from the tuna. After he'd made his initial payment, he realised that he didn't actually have enough cash for all the tuna tins. One had to be left behind.
My view was that he probably had enough for his breakfast anyway and the extra tuna was unlikely to be missed.
