"I wouldn't turn down something to eat, if you're not cooking," Greg wasn't ashamed of taking a hand-out, especially with how inadvertently drunk he'd managed to get. Sloppy of him, but he hadn't really been paying attention, while he was talking with Ray.
He was also intrigued by the tone of the 'or something' Ray had tacked on the end, but he wouldn't ask. Not until the kids were put down, so he could harass Ray properly for it.
