A reference to the 1993, coming of age/gangster movie, A Bronx Tale. In the movie, there’s a scene involving the local mafia don, Sonny, and a rowdy biker gang in a local bar. After the gang assures Sonny that they only want a drink, Sonny allows it. Soon after, they trash the bar and disrespect Sonny, so he locks all the doors and tells the gang that they can’t leave and proceeds to beat the gang down with his henchmen.
