This is all being staged for a bailout, or some sort of favorable legislation from the current administration. They want people to start complaining to their elected officials.
The USPS is in a "slow down" mode. The only thing that they seem to deliver on time anymore are Amazon packages. From what I've observed, they'll pick up packages from the sender, but not scan it. After they park it for a day or two in a local Post Office, they'll finally scan it, and it will go to a regional hub, where it will be parked for another day or three without moving. Then they'll put it in the "stream" and allow it to proceed through the system. End result is a 2-4 day delay.
I have noticed that the local idiot Postmaster who threatened to call the police on me for showing up at the Post Office (after he hung up on me during a phone call) has disappeared. At the time, I let him know that it was a stupid move, as he was very easy to locate (yes, he was this stupid). He has been replaced with an "Officer In Charge" who is even more incompetent, and does as little as possible. This OIC probably isn't on site either, and is probably trying to run things from behind a desk in Chicago.
