Our postie is pretty good (not as good as the old one who was brilliant), we do have two different ones who both do their round running so no chance of catching them! However they do leave small parcels in one of my re-cycling bins (they've got lids on them) & leave me a note. Sometimes parcels are left next door if I'm out even by couriers.
Where I lived before our postie was brilliant, took letters to post, knew everybody, even left post for me, after re-direction had finished, with my neighbour, he knew we were friends & thought she would have my address, she has.
The worst example I had was a meat order,around £100s worth left on my doorstep, in full view, despite me leaving a large note on my door asking him to deliver next door, I couldn't wait in as Hospital had rung me to go in to see my DH who was seriously ill. Luckily I lived in a Park Home with lovely neighbours in a very safe area, I let company know & they were very apologetic & said that should never happen, I believe they changed courier.
What annoys me is often sit at my dining table & can be seen when the walk up my path, the good ones knock on the window as they go past so I can get to my door.
