Yes the post office is slow and does things backwards… we mail a local letter and it travels 2 hours north to the Twin Cities before coming back… the workers at the local office used to separate that mail and keep it in town but lack of workers forces them to send it out.
Our rural carriers use their own vehicles and have to make 4 to 6 trips back into town to fill back up with Amazon packages. I know Target was shipping everything through FedEx but now half of their packages start with FedEx and get transferred to USPS for final delivery.
On the other hand I prefer USPS for packages because if they need to be signed for, UPS and FedEx are both a half an hour away for me. Just today I had a delivery from KMV arrive. I realized I never gave him my current address, he had my previous house, which he shipped it to, but being I was from a small town and had a package or two delivered to my parent’s home, the postman knew where to take it

Luckily I’m going out to eat with Mom and Dad tomorrow so I can get my two engines
