I carried mail for 31 years. The Postal Service, admirably, hires every kind of screwball there is as long as they can read an address, or screwballs with a lot of veteran's-preference-points if they can't. As our friend Stricky used to say, shaking his head at the inane patter du jour, "We've got 'em all down here." And durn near every one of us considered our duty sacred. We even had a name for it: "the sanctity of the mail." So no matter what brand of personal idiocy we subscribed to, we got the mail through.

But maybe other things have changed too. Maybe there's some new Religious Jerkwad Freedom Initiative that's allowing letter carriers to discriminate and harass on the basis of the deeply held belief that some people are too icky for mail service.
I watched the video of the carrier in question. It all started when the gentleman tried to reach for his mail when the entire residential gang box was open instead of waiting until he could use his own key. This is a postal no-no. I used to cheerfully remind grabbers that I was so sorry, but I couldn't allow it because of security concerns, which I was sure they'd understand, but I'd be done in a jiffy.
"But you just handed that lady her mail!"
"Yes, but I do know who she is," I'd say, usually without actually adding And she gives me twenty dollars at Christmas time.

Because I am a nice person.
There are a few legitimate reasons to quit delivering your mail. If, for instance, your unrestrained wolf hybrid threatens me, that's it for your grocery circulars and election flyers. Even more fun, I can quit delivering mail for the whole block. That's the trick that usually gets your attention. Unfortunately for me, I'm supposed to deliver a Bad Dog letter to you first, to explain things.
Not sure the Postal Service thought that one through.

The second thing that was disturbing was that the asshole in this case was a black woman, which goes completely against the narrative. I count on black women to have a much better grip on matters of justice, and although it is never fair to generalize, I'm still disappointed. If some representative of the Postal Service is going to go rogue like that, I want that person to be a recognizable deplorable of some kind. Any of your standard villains. Or at least a man.
