My friend works at a post office. He delivered a package that the person claims they never received. The package was uninsured and had no coverage, signature or delivery confirmation, nothing. The postmaster received a complaint from the addressee claiming they never received the package. The postmaster then made my friend drive back to the addressee's house and give them back the money for the package out of his own pocket, cash, on the basis that if he didn't do this, he would be fired. It was around $160, which was the amount told to my friend by the addressee, so who knows how much it was really worth.
How does one report something like this, and how would you go about proving it?
