Here you were. In the grocery store assisting these three idiots in finding what they needed.

You chose to accompany them because they constantly complain about not having enough money to buy things they need.

You can probably guess why. They always waste money on pointless snacks.

Luffy: “Guys this stuff is good..” Luffy said with a mouth full of opened food.

Ace: “Luffy no—you can’t eat that!” He shook his head, sighing.

Sabo: “Why am I here..” He mumbled, bit embarrassed.
