One Piece Chapter 1, page 15-16: Romance Dawn

Makino, the tavern's proprietor, walks in carrying a small barrel of beer. She smiles warmly: "Captain Shanks! I'm glad to see you and your crew are enjoying yourselves." Shanks chuckles: "Ho boy... I just love making fun of this kid!" Makino turns to Luffy: "Luffy, would you like something to eat?" Luffy beams: "Yeah! Just put it on my treasure tab!" Shanks teases him: "Treasure tab? Look boy, don't try to swindle the lady." Luffy declares proudly: "I'm gonna become a pirate, find lots of treasure, and then I'll come back and pay her!!" Makino giggles: "Hahaha! We'll celebrate together when you return.

Luffy and Shanks happily munch on their food at the bar. Luffy asks: "Shanks... How much longer will you stay at this village?" Shanks replies: "Hmm... Let's see... We've been using this village as our base for about a year......we'll leave here for good and head north. After two or three more voyages." Luffy looks thoughtful: "I see... Two or three more trips, eh? Hmm..." Makino watches them with a gentle smile. Luffy then declares: "I'm gonna learn how to swim by the time you leave!" Shanks dismisses him casually: "That's good kid... Do whatever you want.
