For service....well, my first hope was that I would be lucky and nobody would come to the door. If they did, I only 'worked' with tracts. I simply said, "We're in your neighborhood sharing these with your neighbors"....handed it to them, said 'Thanks' and walked away. It was all I could ever muster.
For the school...that never bothered me. I figured everybody else there was doing the same lame sh*t and wouldn't care what it sounded like. Besides, it didn't take much thought to act like a parrot and read from the publications. As long as you read verbatim, you couldn't go wrong.
