We normally get Cold Callers trying to sell us Insurance here
What I normally do, is let them make an appointment to see me... let them drive to my work, go thru there whole sales pitch, go back to there office, do an entire financial profile on me, make another appointment to see me and when they get back here, I say "Sorry, I'm really just not interested"
...
I know it's a little evil of me BUT I'm sick to death of these people...
