The USPS can not even deliver their so called Priority mail on time. Mailed a Priority 8x11 cardboard envelope on Feb. 3 from Colorado to INDIANAPOLIS, IN. It went to Houston and sat there until Feb 7. Finally got delivered on Feb. 9th.
Also, have you noticed there is no way to complain to them?
I could write a book, lol. I bounced around, doing odd postal jobs while going to college. One morning, we had just finished sorting the letter mail for the letter carriers to come get, and the 7:30 mail truck brought another sack of letter mail from the big office. I started to jump on it, knowing we could knock it out before the carriers came for their last pull and could get that mail delivered today.
The Postmaster himself stepped in and said that mail would wait for the next day, as he had no obligation to deliver it until tomorrow.
This is the same Postmaster, who at Christmas time gave each of us a bright shiny dime to get a hot coffee from the vending machine. A dime, wow, was I ever impressed.
