A/N:

This was inspired by one of those OTP prompt things on Tumblr. Unfortunately, I was going through hundreds at the time, and didn't save the link anywhere. So I apologise for not including the source; I have tried to track it down again, to no avail.

First Zoro and Sanji fic and first OP fic! Disclaimer: I'm not Oda-sensei, the original characters belong to him, not me.

Enjoy! ^^

Onwards!

"You're cheating." Zoro grunted, slipping the menus back into the stand by the till.

"How dare you, Mossy." Sanji replied, scandalised. "I'm an honest waiter here, serving honestly, and collecting tips honestly."

"Liar." Zoro turned to him. "You're shaking them down, or something. Thief."

"Don't," Sanji prodded his chest with one delicate finger. "Make such accusations without any proof. If you're so convinced, why not shadow me for a while? Maybe you'll pick up a few sophisticated skills in the art of conversation, and waiting tables."

"You piss me off," Zoro seethed. "You've only been here a month. Stop acting all high and mighty."

"I've been here a tenth of the time you have," Sanji sang, heading towards a group of girls who looked like they were ready to order. "And probably accumulated double the amount in tips."

"Zoro!" Chopper called from the kitchen. "These soufflés are for table fifteen."

"Thanks, Chopper." Zoro shook his head, reaching for the plates.

"What's the matter?" Chopper panted, catching the look on his face.

"Sanji." Zoro muttered. "How does he manage to get so much money at the end of the day?"

"Not this again..." Chopper sighed, heading back to help Usopp. "Just give the soufflés, go on."

Zoro shifted the desserts on his arms, and spotted another well-dressed couple by the door. Standing up straight, he approached them, balancing the soufflés carefully.

"Good evening. Table for two?" He smiled warmly.

"Yes, please." The woman flushed slightly, blatantly giving him the once-over.

"Right this way," Zoro dipped his head, and motioned them to follow. On his way to table fifteen, he picked up two menus, and led the new customers to their table.

"We'll be with you shortly," He nodded at them. "And if you have any special dietary requirements, just let us know."

Sanji sidled up beside him, taking the desserts from his hands effortlessly. "Table fifteen, right?"

"Hand those over," Zoro hissed. "They're mine."

"Hey, now," Sanji murmured. "I'm just helping you out. You've not had a break in two hours."

"Neither have you." Zoro pointed out.

"I was raised in the kitchens," Sanji smirked. "You go first. I'll take mine after."

"I don't get him," Zoro muttered.

"Get who?" Nami barely looked up from her notebook.

"Sanji."

"What's not to get?" She hummed, tapping away at the calculator. "He's brilliant."

Zoro scowled.

"Is someone jealous?" She giggled.

"He gets so many tips!" Zoro practically whined. "Like... I'll maybe get a few coins from the average table, if I'm lucky. And I'm not a bad waiter, Nami, you know that. This guy, I've seen his customers slip him fivers! One even gave him ten!"

Nami's eyebrows rose at that.

"And he's not even a waiter, really." Zoro went on, folding his arms. "He's a goddamn chef."

"Whatever he might be, it's lucky he moved here when he did." Nami said seriously. "Since Franky and Robin left, you were the only regular we had until he came along. He's humble enough to step in and wait tables on the busier nights if Usopp and Chopper have the kitchens under control."

"Yeah, yeah," Zoro yawned. "The guy's a fucking saint."

"Every bit of his heart's in cooking." Nami said gently. "Even if he's just delivering the food to someone's table. His customers, I'm sure they can sense that."

"Or he's just flirting with them." Zoro said suddenly.

"Zoro," Nami replied in a disappointed tone. "Really?"

"No, I'm serious here!" He was nodding now. "He makes a direct beeline for the female customers. And then obviously, with him looking and acting like Prince Charming all the time, and speaking French- it makes sense!"

"You're ridiculous." Nami shook her head. "You're over-analysing this, anyone can see that."

"There's money at stake here, Nami." Zoro grumbled. "You of all people should understand."

"Got that right, sunshine." She grinned. "Break's over now. Get back to those tables."

"Okay," Sanji slipped his apron off. The doors were locked, and the restaurant was quiet now. "Let's do this."

"There's really no point," Zoro sulked, loosening his waistcoat. "You're just doing this to annoy me."

"Is it working?" Sanji snickered, reaching into his pockets. "Hmm..."

"I've got," Zoro looked down at his own takings, adding up quickly. "£9.53."

"...£22.40." Sanji replied, laying all his cash out on the till for Zoro to see.

"I figured out how you're doing it now," Zoro folded his arms, glaring at the blond. "For this to be fair, we need to serve an equal number of female customers."

Sanji shot him a puzzled look, before bursting out in laughter a moment later. "You're taking this too far, Marimo. As if I would resort to such tactics."

"You head straight to them," Zoro insisted. "It's not a level playing field. Of course they'd tip you more if flirt with them the way you do."

"Zoro," Sanji clapped him on the shoulder, meeting his gaze. "Why is this such a big deal to you, hm?"

Something pulsed in his throat at the touch, and his tone of voice. Zoro's eyes flicked down to Sanji's lips before he could stop himself.

'Holy shit, it's been a long night.'

"It's a competition," He willed himself to stay focused on Sanji's eyes. "I never back down from competition."

"Good to know," Sanji nodded, stepping back.

"Plus, there's money to be had. If you're making more of it, I wanna know how."

"Tomorrow's Friday, right? I doubt they'll need me in the kitchens, and Luffy's booked the day off, so it'll be just you and me again."

"Joy." Zoro replied drily. "So what?"

"I'll make you a little deal then. I won't head to a single table with a woman at it," Sanji vowed. "Unless there's physically no other choice. I'll leave them all to you."

Zoro narrowed his eyes in suspicion. "You sound confident, cook."

"I am," Sanji leered. "I'm still going to win tomorrow, and bury all those pathetic theories of yours."

"I look forward to it," Zoro glowered.

"You and me both, Mossy."

A/N: This one won't be long! But then again, that's what I always end up saying! Please leave a comment if you made it this far! See you next chapter! ^^
