In addition to everything else: for weeks our building has been receiving packages addressed only with a name, a number, S, and the zip. The name is someone who has never lived here and may not exist. There's no apartment number. Our street doesn't start with S, if anything the S is for South. It's obviously some kind of fraud, because what's in the packages are little metal clips to clamp the starting tape holding stuff on a pallet. Not anything for residential use. They ship from various Amazon warehouses but through USPS. We can't get the mailman or Amazon people to return them and the Amazon return process only works if the unwanted package is addressed to you, not some random name.
But I'm now sure as hell that USPS isn't going to let anything as trivial as an unclear address stop them from delivering the package SOMEWHERE. Anything to call it "delivered."
