For me also the change to "smart shop", i.e. you scan and bag your groceries as you walk around, had meant the end of plastic bags for me. I now have to think for a second how many bags I need beforehand, not just grab them on checkout. These days I always have a few reusable bags in the boot of my car that I grab on my way into the shop. The big sturdy rectangular ones that fit snuggly in a trolley and then straight into the boot of the car. And a more insulated bag for cold items. On top of a foldable one in my work bag for small items on the way home if I commuted by train. I hated the old flimsy but free bags they had in the UK, I did not trust them enough to reuse. They quickly ripped, could not contain anything runny/liquid, etc. I am glad they disappeared, both for environmental and personal reasons.
