@whatsallthispod.bsky.social thought you needed to see this
I always use bags from a more upmarket supermarket to subtly show the other customers I am better than them. I use Tesco and Sainsbury's bags in Lidl/aldi. And Waitrose bags in Tesco. What do I use in Waitrose? A Harrods jute bag. I doubt they notice, but I know.
