I had almost the exact thing happen to me at one in Nashville a couple of years ago. Was a real A-hole yankee, white feller though. He chewed on the waiter over a piece of bacon he wasn't supposed to get, then chewed on the female manager. My wife had to call me down, I chewed on the A-hole Yankee. I later spoke with the manager and my wife talked to the young waiter. Manager acted like she was used to it. Damn, makes me mad thinking about it!
