I find the opposite - in FL. I've had 3 different carriers in the 20 years at my current home, and they are all lovely and about "six-sigma" perfect.
I cannot remember the last time something went missing inbound or out. Every now and then I get a piece of junk mail stuck on one of my pieces, but it's meant for a neighbor.
I have a small business, so I've also sent and tracked thousands of first-class packages over the years, and my need to file a claim or investigate a missing item is super rare, even then, nine times out of ten, it turned up.
