Sounds like someone some serious anger issues:

It’s an age-old and vexing question: How much is it fair to shave off the tip at a high-end restaurant to signal dissatisfaction with the waitstaff? Two percent? Five percent? Should you stiff them? For leveraged buyout king John Castle the other night, the answer was easy: Just crack the little fucker’s finger.

Castle, 76, is the chairman and CEO of Castle Harlan, a private equity firm. Before that, he was CEO of the investment banking firm Donaldson, Lufkin & Jenrette. His is a positively Romney-esque tale of the value of raiding companies to extract value—his business acumen has subsidized a lifestyle that included purchasing the Kennedy family’s Palm Beach, Fla., compound in in 1995 and hosting magnificently lavish weddings there for his children, complete with Trader Vic’s catering and Mar-a-Lago luncheons.

And on Saturday night, according to a complaint filed with the Palm Beach Police Department, he reacted to subpar service by calling his waiter a “schmuck” and breaking his finger. Castle and his wife Marianne, the complaint says, were having dinner at Club Colette, an elite Palm Beach private dining club (restaurants are for poors), when their waiter Paul Kucik made the unforgivable error of bringing them the check. Which is vulgar, I guess? From the report, which was first reported by the Palm Beach Daily News:

Romney-esque? More than you might think. Castle has been donating money to Romney and actually does all his donations to the GOP. Supporting a candidate or even party like that is enough to make anyone angry!
