Ron is the business agent for Kansas Moonshine, a rock band.  He is also the agent for another popular Midwestern rock group, The Litigators.  Ron negotiates a deal with a Kansas City promoter to have The Litigators play after a professional football game.  The promoter was willing to pay $250,000 for both groups to play after the game; however, Ron talked her into booking just Litigators for $175,000.  Given his contract with Litigators, Ron made more money under this arrangement.
