This guy's beef was that I knocked rather than ring the door bell while delivering to his neighbor. The driver had me go back and ring the door bell just to try and shut this guy up. It didn't work. This guy wanted names which was refused. So he started taking pictures which the driver told him not to do. Anyway this guy then follows us on to the next street. He didn't follow us beyond that street however. The driver just called it in to the center. If this guy had continued to follow us, the center would have called the police from what the driver was telling me. The driver even told him that it was basically none of his business. This guy told the driver that because he was their neighbor that it made it his business. Basically my first time of coming across something like this while out there.
