I conscientiously filled in my 2001 census form, and posted it in one of two postboxes outside the Post Office which had been newly installed specifically for franked mail. But it turned out that the Communication Workers Union hadn't agreed that members would empty the new postboxes and they were plugged. Though with a gap that was big enough to slide an envelope through. So I phoned to say what had happened and wasn't sent a replacement form to do again. The postboxes are still there, but the Post Office has moved over to a smaller building on the other side of the road. I think my 2001 form is probably still in the box where I posted it....
