When Nami discretely offers to keep their more rambunctious (and curious) crewmates busy for an hour or two in addition to unrestricted use of the storage hold - all for an astronomical fee, of course - she doesn't really expect Zoro to agree without batting an eye.
To her surprise, he merely tosses her a folded wad of beli pulled from his haramaki before striding off with Luffy draped over his shoulder. She fumbles and nearly drops the notes, then pulls the wad apart to count it as the crew heads toward the ship. She snorts when she discovers that he's actually given her quite a bit more than what she asked.
Sanji glances down at her takings and fishes in his shirt pocket for a new cigarette. "Should you really be encouraging him?"
"Easiest money I ever made," Nami muses, then smirks at him. "Besides, would you prefer walking in on them in the sleeping quarters? Or the head? Or the-"
"Okay, okay, Nami-san, I get your point."
She sees his eye twitching and laughs. "I thought so. But seriously, I ought to be charging you too, Sanji-kun."
"What? Why?" He demands, giving her a betrayed look.
"Because I'm guaranteeing you a Luffy-free kitchen for the next two hours."
"Oh." Sanji considers this. "Tell you what: I'll whip up a pre-dinner snack to keep Usopp and Chopper occupied, and we'll call it even."
"Deal," Nami agrees, and then takes his proffered arm, laughing as he beams brightly and adds a spring to his step.
