a few years ago I has a crazed census worker that would not leave me alone! Banged on my door, cam back over and over again... it was the the worse harassment i have ever endured. Then it was not enough to have filled it out then she wanted to go over all the question i told her to F#$k off and slammed the door. She knock for a half hour before I opened the door and told her to leave or I was calling the cops. She left, but was back the next day knocking again. I just gave in and answered her questions. It was unreal! Never again will I give in... FUCK THEM!
