Ok, I get the "bring your own bag" thing. I always bring my own bag, My question is, if I buy an item of clothing from, eg, M&S, AIBU to expect they will wrap it in something like tissue paper, so that it doesn't just go in my bag with everything else? What if it gets marked, or damaged? How do I return it? I don't mind paying for one of their bags, but surely the point is to reduce the use of plastic bags? Why can't they just put some tissue around it (like many independent stores do?). M&S and Debenhams are two of the biggest culprits here. Debenhams actually gave me an unwrapped bra to to take home!! I had to stuff it in my pocket!!! (didn't have a spare bag with me that day).
