The first day the food truck is active, and they're handing out free sandwiches to the workers who helped them load the heavy gear onto the truck. One of the sandwiches is burned, and Carl's son Percy doesn't understand why they don't give it out anyway because its not like they're being paid for the food. Carl takes Percy aside and explains to him just what being a chef means, and why you don't give your customers anything but your best effort, always.
Carl: "I may not do everything great in my life, but I'm good at this. I manage to touch people's lives with what I do and I want to share this with you. Understand?"
Percy: (a little awestruck) "Yes, chef!"
