The whole bag thing is a mess
My granny and my mother always went shopping with a bog of their own. Potatoes and sprouts (loose), sugar, flour, all went in the bag. Eggs, would you believe, were in a paper bag.
Then came the supermarket. Bags for free. I've never taken a bag when I went shopping (But then men don't, do they?)
All of a sudden we have to save the planet. Bags have got thinner and thinner until we are implored at the till to "double them up" for anything heavy or containing liquid
The bags for live, or multi use, still get left at home and it's really not until there's a penny or twopenny charge for plastic bags that the number used will fall
But of course the first supermarket to do it will lose trade
