The rotating "chore" schedule on Mother Base had left you in charge of cooking for the week. You'd been cleaning up when he walked in, watching you for a few moments before stating that you weren't a half bad chef. He was underselling it by a lot, you were a great cook and he'd enjoyed the food thoroughly but he wasn't willing to swallow his pride and admit all that just yet. Eventually asking: "You ever considered getting out of merc work and being a cook?"
