You know the score. You pop into a shop, to buy a sandwich. You carry your sandwich and drink to the counter, and they insist on giving you a plastic bag to carry it in.
WHY!
I can carry it to the counter, I can carry it out too.
Pret today even threw away a small plastic bag when I said “no thanks”. Rather than save it for the next person. Presumably because it was crumpled. Grrr!
