Mike Barth's patience with some nameless jerk earned him a payday of epic proportions.
Today, Barth is a multimillionaire thanks to his level head. Because after he let that stranger take cuts, Barth stepped up and bought the winning Mega Millions ticket. Had he made a big fuss, he'd have bought the stranger's losing ticket instead of winning a whopping $319 million—a sum he's splitting with six coworkers.
Of course, being courteous and restrained in line won't guarantee you'll win the lottery. But this is a great instance in which a courteous guy did win, and we're happy for him.
