Not a Tom Cruise related mission but Mr J told me that one of his friends had bought a rechargeable watch with a stop watch that lit up. I said that it sounded like my Garmin. The trouble was that the budget was £8. I did check the stalls on Deptford Market but there was nothing available.

As for the rest of the shop it was pretty standard apart from a long discuss looking at the sugar content of every variety of granola and muesli.
