Cook

Chefs are people who cook for passagers or crewmates on ships, or cook for customers in resturants. All pirates can be hungry, so many of them need a chef to cook food to fill their belly. Marine bases and Marine ships need them to feed the soldiers to keep them healthy. Commercial ships or cruise ships require them to feed the passengers.

Story
After the Kuro arc, the Straw Hat Pirates meet Johnny and Yosaku. Yosaku was sick from scurvy, so Nami intructed Usopp and Luffy to make soup to cure Yosaku. Yet the crew had no cooking experience, so Luffy decided to find a chef for his crew.

Baratie
Upon arriving at the Baratie, the ocean-going resturant, Luffy met a man named Sanji, who was the assistant head-chef. There he also met the restraunt's owner, Zeff, along with two partners named Carne and Patty. Luffy was impressed with Sanji's compassion towards Gin and tries to get him to be his crew's chef, but Sanji refuses many times.
