Imagine getting back to the delivery office and telling all the other postie's what you did. Nobody would believe you
I used to live in a shared house and one girl had stuff delivered by Yodel almost daily. I often found the packages under my car and thought they were doing it because it was out of the rain. One day I happened to be looking out of the window when a Yodel driver pulled up and threw a package out of the driver window. It bounced off the doorstep and went under my car.
