This doesn’t happen to only black technicians. Used to do renovations before retirement and some folks are just a real PITA. Especially in the southern retirement states. Folks from “up north” were always the worst. They watch you like they have a clue what you are doing, give advise and make demands as if they know what the job entails and then question every line in a billing as though every tech is trying to rob them blind. And Then there are the transplants from some union state that always points out”THAT’S not how we did it up north”. Damn glad I’m retired.
True, plenty of idiots out there. But sadly a high percentage of idiots are also racists, it’s a very overlapped Venn Diagram. I’m on a community social app Nextdoor, it’s disappointing how often people on that thing post “danger alerts” that are “black guy walking down the street”. But even without the racist idiots, there’s still just plain idiots.
