This happened to me at a coffee house in Ukiah one day. I replied, "Is this what passes for Christain love with the Jehovahs Witnesses in Ukiah? You should be ashamed of yourself for even using the name Christain!"
A man asked asked what it was about after commenting on the fact that the woman had simply allowed the door to shut in my face in order not to acknowledge my presence. In front of the witness, I gave the anti-witness to the others in the line about shunning and twisting of scripture and why the woman was acting like such a fool.
She left the line for coffee and left the coffee shop in embarrasment, not meeting anyone's eyes.
And no, I didn't feel sorry for her not one bit.
