People have different appetites, and that's fine. Needing more food is not a lack of manners. But the problem starts when one person eats as if nobody else exists... In a shared family space where older relatives are doing the cooking, and someone else is paying for the groceries.

This sister's boyfriend's behavior is disrespectful and inconsiderate. Even though the grandmother enjoys cooking for them, that doesn't mean she has unlimited energy and unlimited access to groceries just because one guest keeps eating everything.

Sharing food requires awareness of the existence of other people who also want to eat. If someone is still hungry after eating their portion, they can ask if there is more. They can offer to cook more, or they can even buy the groceries. What they shouldn't do is assume that the food on the table belongs only to them.

This boyfriend isn't just eating a lot at meals. He's eating food that is meant for everyone. If steaks were cooked for the whole family and he ate the last one before all family members got to eat one, then that's not an appetite problem. That's a consideration problem.

It's understandable that the sister said something to him. If his girlfriend isn't stopping him, then someone should. Raising her voice wasn't ideal, alright. She could have said it more calmly. But at least someone pointed out his behavior. Nobody else seemed willing to address it, and it had happened multiple times. If he's going to stay there, eat there, and benefit from everyone else's labor, he should at least contribute to groceries and ask before eating more. And that is basic manners.

AITA for telling my sister's boyfriend off for eating too much?

I'm 19, my sister is 19 too and her boyfriend is 21. It's summer now and we've all come to stay with our grandparents for a couple of weeks.

My sister's boyfriend is a big guy and eats a lot. I realize this sounds bad, but it has nothing to do with his appearance or weight. He consumes

food on the table as though no one else needed it, which is the issue. Grandma enjoys cooking for us, but she is no longer able to prepare large servings every day. I purchase groceries,

cook and assist her in the kitchen, but neither of us can spend the entier day at the stove.

Over the last week days, he's finished off almost everything several times, chicken, pasta, sandwiches, snacks. A

couple of times, Grandpa came into the kitchen and there was almost no food left.

Three days ago, I made steaks for everyone. I left them in the kitchen while I helped Grandpa in the yard.

When I came back to eat, the steaks were already gone. My sister's boyfriend was sitting there, finishing off the last one.

I didn't yell, but I said it in a raised voice and clearly annoyed. I told him he eats too much of the shared food and if something is cooked for everyone, he should ask before taking extra. I also

said that if he's going to eat here every day, he should start chipping in for groceries and think about more than just himself, because Grandma gets tired and food doesn't just appear on its own.

He got offended and left. Later my sister said I was greedy and had embarrassed him. Now they both don't talk to me and avoid.

Maybe I could have said it more calmly. But this wasn't the first time he'd eaten almost everything, not chipped in for groceries (he never does) and left the rest of us without food. AITA?

Swain Vishatrove NTA. Finishing every steak before everyone has even sat down isn't "having a big appetite." It's bad manners

SweetpeaKitten1 If he's hungry enough to eat multiple people's portions every day, he can help pay for the groceries.

LadyF16 NTA. There's no way anyone walks into a kitchen, sees a pile of steaks, and thinks it's just a snack free for him to consume entirely.

Your sister isn't actually mad at you. Your sister is embarrassed by her boyfriend's behavior and doesn't have the guts to call him on it like you did, so it's easier to be mad at you than have a conversation with him.

DearGlitterx NTA. That is basic manners. If food is cooked for everyone, you do not take extra until everyone has had a plate.
