I was standing behind Clive James in a supermarket food queue once and, rather than engage him in discourse on Piero della Francesca, I merely scrutinised his basket. I was surprised to find him buying sausage rolls with tomato.
It made me seriously think about how I could live a small part of his life for a mere £2.49 (plus loyalty points). Today’s invention is a website which can be used by celebrities to publicise what they consume (whether food or books or whatever).

They upload their receipts (in return for extra discount and publicity). The rest of us get some kind of vicarious post-twitter contact with the media pantheon -and their shopping.
