Ha, ok.
So what happened then?
In fact, i'll tell you. You received the printer, but saw that you hadn't signed for it and that the PF man had, so you took the opportunity to try and tell Parcel Force it was stolen because you knew the driver shouldn't have signed for it and they wouldn't have a leg to stand on, so you'd get a free printer.
i thought it was a bit odd from your first post - i mean, how many people do you have walking through you back garden?
