What method does Johnny use to organize and run his business in the novel, The Washington Square Ensemble?

The underlying principle of Johnny's business is individual anonymity: He has given each of his salesmen a name, and they know each other by those names. Only his lifelong friend, Holy Mother, knows Johnny's actual name; in the opening chapter, when he describes his operation, Johnny plays upon the Italian stereotype, remarking that his name is "Enrico Spaghetti or something like that." His seemingly uncanny ability to "name" the other members of the group gives him power over them; each of the other major characters accepts his individual name as the most fitting choice. Although his "salesmen" are impressed by his apparent knowledge of their inner thoughts and feelings, Johnny reveals that this knack is actually a combination of careful observation, some limited research, and basic "street smarts."
