One Piece Chapter 46, page 1-2: The Uninvited Guest

At the ocean-going restaurant Baratie, Sanji is in the middle of a heated argument with the head chef, Zeff. Sanji demands to know what Zeff means, saying, "Hey, you damn geezer. I'm the assistant head chef of this place. So just what do you mean exactly when you say that I'm not needed!?" Zeff bluntly responds, "You cause too much trouble with the guests, and if they happen to be female, you drool all over them. And as you probably know, none of the other cooks want you here as well. So whether it be a pirate or something else, it's just better for you to get the hell out of my shop." Zeff continues to insult Sanji's abilities, saying, "You also can't cook a decent meal to save your life. You're just unnecessary baggage, holding this restaurant down." In the background, Luffy, Zoro, Nami, and Usopp watch the drama unfold from their dining table.

Sanji reacts furiously to Zeff's insults, grabbing the old man's collar and shouting, "So that's what you wanted to say to me all along, you damn geezer!? Ignoring all your other comments, if there's one thing I won't stand for, it's someone insulting my cooking! No matter what you say, I'm staying here! Got that!?" Zeff immediately retaliates, kicking Sanji hard and sending him crashing to the floor. Zeff mutters, "Hmph," while Sanji groans, "...Damn it!" Luffy, Zoro, Nami, and Usopp continue to watch the violent exchange from their table.
