Gluttony gave Greed a rude hand gesture and just sat there pouting at the thought of not eating McDonald's right then. He smirked, swallowed a mouthful of popcorn, said, "LAY OFF MY FOOD JACKASS," and greedily grabbed the entire bowl. He held it close to his body as though it was a precious infant. "You bring your own damn food."
That just ticked him off. No one ever touched Gluttony's food without his permission. Not even Greed or Lust. They didn't have special privileges just because they were his favorites.
