Courtland Street is a seedy part of town. It's where there's back room gambling, prostitutes, and dives. Sonny has a lot of control here, as people need bookies and money to support their bad habits.
Sonny: This street never sleeps.
Jason: Should we make a few stops? I have to collect on a few people.
Sonny: No business tonight, Jason. We have company.
Jason: I don't want to upset you, but I see Mike hanging around here all of the time.
Sonny: Are you giving him money?
Jason: (Hesitates) Sometimes.
Sonny: Not a good idea, Jason. You'll never see your money again.
Jason: (Shruggs shoulders) It's just money.
Sonny: (Holds up hands). I don't want to know what Mike does. Just keep an eye on him.
Jason: I always do.
