He could be a stealth Mormon. They do that sometimes. They try to dress all hip and with it (you know, For The Kids) and then sit backwards in their chair with their hats on backwards and talk about rapping.
... Wolfgang watched a lot of American TV growing up.
Still Wolfgang hesitates, one hand out, before their stomach cramps and they take their half. There's a moment where they try to hold on to some sense of decorum but they can't help it and pretty soon they're wolfing that thing down like they haven't eaten in a week. It's only been about a day, give or take a few hours, but that's a long time when it's your body on the line, and most of their meals up until now have been donated Luna bars and single-serving boxes of cereal. It's probably going to make their stomach hurt but fast food is cheap and filling and hot and they'd rather eat McDonald's than gruel.
They actually lick the salt off their fingers like a cartoon character.
