My other pet peeve is carrier bags. Now I'm quite happy to unpack my own trolley & pack it into carrier bags but I understand that they have the staff to do it for you when the shops busy and you need to hurry through.

BUT I really don't appreciate every single item being put into a seperate bag!!! I once bought a couple of re-usable carrefour bags and before I knew it they'd put them into a plastic carrier bag for me to take home! It's just annoying to end up with a mountain of bags at home, annoying to carry them all in and it's not good on the environment.
