So my USPS guy is really great and has been the same one for many years. We talk regularly.
At my old house the postman was awful and could barely speak english, as we found out later on! (they did eventually fire him- it seems he was a thief too).
We just had an amazon delivery sent by my brother to my son. We have 2 mailboxes on the road, about 600' from the house. He left the package lying on top, across the 2 mailboxes.
We have had stuff stolen like that. We have no snow and it's warm out right now.
Found while walking dog, luckily in plastic shipping bag, as was covered in water from this mornings rain.
Fedex has been much better lately, see the same 2 trucks/drivers now. vs. the random people who left packages in many different places for me to scavenger hunt.
UPS guy , 90% of the time is the same person and he is incredibly reliable. Even after a snow, he will wrap our packages in a clear plastic bag and walk them up the drive a bit to hang them off a branch behind our garbage cans.
