On Mercenary Signature-Seekers

Right now I'm sitting in the window of Kaldi's Coffee House in downtown Columbia.  I am watching this mercenary outside seek signatures for some petition to get something on the upcoming ballot.  Columbia is slammed-- and I mean slammed-- with these dudes right now.  You can't walk down 9th Street without getting accosted multiple times. First, do you think this is how people view traditional, evangelical evangelism methods today?

Second, what is the Christ-like way to handle these requests?  These people are everywhere!
