Very Mean Men.

A bartender wants rid of an obnoxious drunk but not until the drunk has left a decent tip. So the bartender tells the story of two mobster families, the Minetti's who work out of an Italian restaurant in the East San Fernando Valley, and the Mulroney's who work out of an Irish pub in the West San Fernando Valley. Mob war breaks out when one of the Minetti "boys" stiffs Big Paddy's daughter on her tip. We soon see why these hoods are called very mean men
