Sir : In my experience, the "overwhelming choice" offered by supermarkets begins before I even go through the door (Irritations of Modern Life, 17 February). Do I choose a hand basket? Or a half-depth trolley? Or a half-depth trolley with built-in shopping-list holder (on the rare occasion I remember to bring the list with me)? Then there is the "regular deep" trolley. The "regular deep plus new-born baby seat". Or the "regular deep plus older-toddler seat (with or without safety strap)". Alternatively, I could have the "regular deep plus baby plus toddler seats".
When I go with my mum to her local supermarket I can have my own scanner attached to all or any of the above ....
