Shipping a gun. Should USPS/UPS know its a gun?

[realmswalker]

Someone I know just shipped a handgun to the ruger factory for repair via ups ground. He said the lady at the ups counter knew it was a gun as he showed it to her that it wasn't loaded and didn't tell him about any policy or having to ship it next day air. Were any laws broken here? the gun made it by the way.

Nope. This shipping policy is an internal carrier matter.
