Particularly because the stupid system wouldn't let me pay cash into my bank account using a paying-in slip - apparently you have to use a card, and then the PO person has to weigh each bag of coins, then sort out how much you're paying in himself, rather than ticking it off on the slip. Obviously that's going to take twice as long And if I'd known that when I tried on Monday (when there was no-one else there) I wouldn't have needed to go back today.
