If I were the MC, I wouldn't do anything. I wouldn't help, I wouldn't eat, and I would start walking in the general direction of the nearest town. Mr. Bossy Boi might not be interested in being a decent, open minded human being, but I'm sure there's plenty of people to convince in the nearest town.
Dude is over here acting like asking for shampoo and conditioner or picking beans out of rice is some huge deal. Just because you like it and it works for you, doesn't mean it works for everyone. Also, you're not even hearing the MC's side. Dude gives me the ick.
Also, the dad is a jack@ss. He was an absentee parent and now blames his kid for looking for love and affection in all the wrong ways?
I think the MC is being such a good sport right now, really.
