Nathan takes the cigarette with a nod of thanks and smiles. "Sounded good to me, but I'm not the one to ask." He pulls out his lighter, lighting first Kate's then his cigarette. "If you think it needs work, the one to talk to is John. He'll help you figure out what's wrong."
Taking a draw on the cigarette, he blows smoke off to the side and asks, "What can I get you?" There are other things he wants to know, but they can wait until she's been served.
