While Booker did look like he was in a constant state of brooding, it usually was because he was brooding, much to the amusement of those close to him. He eyed the women, lifting his drink to his mouth and taking a sip while he considered his answer. "Once or twice. Might have brought in a mark or two. Used to run a pawn shop too and more than once had to report a pawned item that was obviously stolen."
There was also the whole mess with Cerberus (or was it Hydra now?). And there were certain illegal shenanigans which shall remain nameless.
