One of the things which catches U.S. tourists out here in Britishland is that retail outlets frequently do not offer bags to carry out any purchases — or, if they do, they charge 5p each for the wretched things. And it works, if the goal is to reduce trash.
Now Tesco is apparently doing away with the cheap flimsy ones, and is going is issue sturdier bags — for 10p each — which can survive multiple uses.
Now, as Doc Russia reminds me, this is all very well; but it should be noted that the number of disposable bags may well have gone down, but that has been offset by a concomitant rise in sickness from e. coli bacteria infection. Yup… traces of bacteria from fruits and especially fresh meats will stay behind in the bag and be transferred to future purchases.
So if you’re going to do the Green Thing, wash that bag, y’all. And by the way, I’ve been doing this for a long time and let me tell you: canvas bags work better than any of the sturdier plastic things, which don’t handle the washing machine experience well at all. You just have to remember to put the damn things back in the car before you go out to do their shopping (something I fail to do quite often).
