That's exactly right — when I did canvassing, they drilled it into our heads that we were to STICK TO THE SCRIPT NO MATTER WHAT.

I cringed when someone agreed to give, and then I was supposed to say, "That's great — but we're asking people to give as generously as they can. Could you do [double that]?"

Having interacted with canvassers on the street since then, I think that approach is really misguided. I used to stop for them and be like, "Hey, I know how hard your job is! You're doing a great job!" But most of the time, they just keep barreling ahead, without seeming to notice what I just said. So yeah, I don't stop anymore.
