I was just casting my mind back to when I would accompany my parents on the door-to-door work and remember that a considerable amount of return visits/calls were recent immigrants to the country who spoke little English. Once they found the country of origin they would immediately order literature in that language, despite that sometimes these people were just happy to read anything since they spoke little English.
It just reinforces my beliefs that they really prey on the most vulnerable members in society, maybe we should pamplet immigrants at airports to protect them from these people!
Anyone have similar experiences?
