As long as supermarkets provide the cheap bags people will 'forget' to bring their own. In France they stopped ages ago....there was no alternative....you HAD to bring your own and you got little sympathy if you had nothing (as holiday makers we quickly had to learn!).
Its not difficult to get into the habit of keeping a supply in the car.....you have to remember to take your handbag/purse so why not a few bags....oh its all so annoying to watch perfectly capable people load up in Morrisons with a trolley load of thin plastic bags...the staff just dole them out unquestioning.....sorry its a bit of a soap box thing for me!

World Class Museums - why are they free to everyone?
Would you think it was odd if a younger person wanted to befriend you?

My excuse is that we have been moving DD and all her stuff and taken the bags and car seats out so I could put the seats down flat. I won't do that again.
