"Well luckily he's not here, or he might tell me I'm using the wrong fork." Bucky never used to care about such things, but when he finally convinces Oeznik he can help with laying the table and gives himself only one fork with no knife or spoon, he usually gets the Deathly Glare into submission and gives himself more cutlery he ends up not touching. Bucky's made it stressful for himself to eat in, and there's a bit more breathing space when he's out with Zemo.

"Oh-- it's haww--" Yeah, that's probably why Oeznik gives him a knife, so he doesn't put the whole thing in and potentially burn himself with molten hot cheese and whatever else the filling is made from. He covers his mouth and tries - and fails - not to laugh while chewing on his rice ball and swallowing it without burning himself all the way down his throat.

"It's hot..." Don't do what he just did. Not that Zemo would put a whole ball into his mouth like an animal without cutting it in half first.
