The Captain has complained about the catering department overtime and the amount of food being left over and wasted. The Cook suggests that he cooks a large amount of rice in one go, keeps it warm during service at the evening meal, places any left over in the refrigerator overnight and then re-heats it for the lunch-time meal it the next day.
