Yeah. I mean, it depends on the scam; usually the grifter is the person who convinces the mark to do the stuff you need him to do to make the scam work. You know how the word "con" in "con game" is short for "confidence"? That's what a grifter really does. It's not just being good at talking to people, it's getting people to trust you, so you can convince them to do things you need them to do.
