Sidepass: The chip on their shoulders entity known as the "usps" has been horrible for the last 50 years (since about 1971 when the "union" became even more militant than prior!).
I try to never use them myself.
My larger than average list of horrors with the usps and my various attempts to rectify them has been for naught - they (the usps)seem to get worse, more expensive and more arrogant/defiant every year.
Privatization is the ONLY possible solution.
Sad.
