Mao had only managed to eat a handful of chips before James stole a chip. "Wuh! Those're mine!" He pouted, and though he claimed ownership he didn't try to stop any theft, he only sulkily licked the cheese dust from his fingers. James' arm had gone over his shoulders, so Mao's arm went around James' waist. Totally gay looking but luckily James was secure enough in his heterosexuality that Mao could get away with it.
At being told James was going to eat everything, Mao's eyes went wide with worry. "But...but what about me?" The fact that he believed James just showed how fried he was. "I wanna eat too, I want a hamburger too!" Mao whined childishly, staring at his bag of chips as though he was thinking it was all he was going to have and he was trying to figure out how to ration it.
When they made it to the door, Mao wouldn't let go of James, so the two had to somehow squeeze through. Mao found it hilarious, of course, and momentarily forgot about the starvation in his future to laugh like an idiot. The two of them were making a great impression already.
