Stop in for a cup of coffee

I'm lucky. I really like my job, my bosses and my coworkers. Sure things get stressful, but everyone gets along. Everyone has a big sense of humor, and no one back stabs. Truly a rare combination. My top boss is a retired Army Col, taught at West Point at the end of his career. But he's not a typical Colonel, more like that cool but knowledgeable First Sergeant. Rare for an officer. He's the one who pushed me to my MBA and talked the company into paying for it. I turned down an over making more than double my current salary just last month partially because of my current environment at work.
More than double? Not a wise choice for someone so early in their career and pursuing an MBA to get ahead. What would you think “business” would think about that choice?
