Well, here's a slashdot story about a poor guy who got arrested because of a dipwad bestbuy manager in Dekalb, GA.
What makes slashdot so great is that later on, the guy in question wrote up the whole story. So what we have here seems very much to be a moronic power-mad manager who thinks everyone is out to cheat him, victimizing what certainly appears to be a reasonable guy who just wanted what was due him.
Did the guy come back with a gun to address his dishonor? Nope. He's gonna sue, and good for him too!
Something vaguely similar happened to me years and years ago, but I was a dumb teenager doing something stupid (legal, but stupid). Just because you're the boss doesn't make you right. It just makes you the boss.
