Actually, all you have to do is say "I don't want the bag, thank you" and
take the receipt which is proof of purchase, not the bag.

That's what I said, but it seems this isn't an acceptable request by UK
shopkeepers. I've been told, so now I know.

It is in every supermarket I have been in UK.

Sure they offer, even /expect/ you to want a bag, but I've never been told
I have to have one.
