Had a delivery today by post, I was upstairs when they delivered it and so was handed it to the wife. Watched the postwoman walk up the drive and as she got to the gate she waved her phone in the air and then was gone. I looked online later to track the parcels history and at the end was a box that said "Proof of delivery"......... and there was a picture of the bonnet of my car and the hedge!!!
However that would stand up in court had I claimed I never received it I don't know.
Having said that when I had my parcel delivery head on all those years ago {pre scanners} I knew the houses where to {definitely} get a signature and the ones where I didn't have to worry.
