I'm sure you're right about this; in my circumstance the *supposed* backlog was the USPS. If you're expediting the renewal of a minor's passport you have to visit the USPS to confirm you're the parent, take a quick interview, and sign an additional document. That was represented as being a 3-6 month wait. Could be bullshit, but I suspect USPS employees might be easier to grease than Federal passport employees.
My wife's company uses the service often, as employees and clients travel internationally frequently. She sent me there to get this done ASAP. So sitting in the chair listening to his spiel, I had an Angel on one shoulder, Devil on the other. Angel said, Hey man, get up and do a little research, check this out, sounds like this might be bullshit, don't be a schmuck and pay an outrageous fee. The Devil said, Hey, fuckstick, you want to pay the $1200 and get this done now, or possibly get divorced?
As usual, Devil wins.
