USPS rant ( again)

I sell my two Volare's, have some extra parts to sell off. Find buyer for7 WOM in Ca. I box it with two pieces if cardboard, just the size of the stuff. Take it to PO for a shipping quote. She weighs, she measures, and yep $28. Cool. So the guy sends me the $ paypal. I also get hit for the 3% PP fee, thats fine. Take it back to PO and the SAME WOMAN that did my quote says. " I am so sorry, but it is too big to go USPS." WTF is she the damned stupid? Guess so.
So I make 50 mi trip to UPS in another town, and get this, $155.35 to go to Ca. He say yep, expensive to go there, and the box is sorta big. Not near as big and heavy as an AMD windshield that goes from Atlanta to Tx for $200, but....
So I send it on, NOT the buyers fault. I did not lose any $, just that my $150 worth of WOM suddenly became $25 .... less cost of 50 mi trip! ha
I love my USPS. I must have pissed off that worker before!?????????????????????/// She had to have done that on purpose.
Rant over. Sorry.
