sucker game

“It’s a sucker game, unless a man gets inside information from somebody that knows what’s going on. I happen to be associated with some people who’re right there on the ground. They have one of the biggest manipulators in New York for an adviser. Way I do it,” I says, “I never risk much at a time. It’s the fellow that thinks he knows it all and is trying to make a killing with three dollars that they’re laying for. That’s why they are in the business.”

Whatever you do, it's a sucker game.

You are a collector for a hospital or a orphan asylum, or some such sucker game.
