I could be wrong but I don't think it happens as frequently as something like, say the sopranos, makes it seems. violence always costs in some way shape or form. If guys are hurt they can't pay. I think for the most part collections and loans go off with a reasonable amount of peace. There are a lot of degenerates in that world who try to welch and generally act like scumbags so violence becomes necessary far more often than in the regular world (where violance becomes necessary never), but I don't think you have guys breaking peoples legs every single week.
