Every day I listened raptly to customers who felt like talking, and it all added to my education. My ears soaked it up like sponges when one of them, in a rare burst of confidence, or a little beyond his usual number of drinks, would tell me inside things about the particular form of hustling that he pursued as a way of life. I was thus schooled well, by experts in such hustles as the numbers, pimping, con games of many kinds, peddling dope, and thievery of all sorts, including armed robbery.
