USPS Fail

I shipped a steering gear via UPS. When the guy asked me what was inside, I told him car parts. Then he went into this long inquisition about if there were any fluids inside, combustible materials, dangerous chemicals, blah, blah, blah. He said that UPS will yank his franchise if he is found to be shipping flammable liquids; something to do with homeland security regulations, blah, blah, blah. I'm no terrorist. Now, I just tell them the box contains books.
