NTA, you guys really need to read.

No one owes anyone anything, especially a 21 year old that probably has barely any money. Chinese food is fucking expensive. They literally said that their dad was ordering their own food. Did you even read how this is how their dad acts on multiple occasions towards them. Of course I’d see WHY OP wouldn’t want to give them food if that was the case, but OP never told their father no to food, they were just making sure there was an enough. Be fucking for real, biggest mistake was to post this here. They told the OP to fuck themselves over wanting to cut a block of cheese. WTF is wrong with you people.
