For those of a certain (pre-screen) age, and to while away long car journeys, you used to play a game where each player in turn added an item to an ever increasing shopping list...until someone's memory failed them and they were out.

Today was a return to that game for Mr M - "I'd like the same as last week, but one more vegetable soup, and this particular loaf of bread"...of course I could have noted it all down on my phone, but where's the fun in that...
