In Italy it's the same. If we were to believe that everyone they label as "boss" is really a boss or even a capo, there would be more bosses and capos than soldiers in the mafia. I think they even called gangsters like Leoluca Bagarella or Mario Prestifilippo "bosses".

Willie Marfeo to Henry Tameleo:

1) "You people want a loaf of bread and you throw the crumbs back. Well, fuck you. I ain't closing down."

2) "Get out of here, old man. Go tell Raymond to go shit in his hat. We're not giving you anything."
