Damned USPS!!!

So I sent my gas tank to Elswick Cycles to get Frisco'ed, the petcock moved back, the filler cap moved forward and new mounting points added to it. The gas tank filler bung was in a different box. I check USPS tracking last night. The filler bung made it, the gas tank is coming back to me. Apparently even though I printed off 2 copies of the mailing address as given to me by Elswick the PO can't deliver 2 packages to the same place. That tank wasn't cheap to send and now I gotta do it again!!! Yeah, I'm a bit pissy!!!!
