I have experienced some similar.

This is a very interesting thread.

You have to see the other side of the story, though. The members of the family aren't necessarily "ungrateful bastards".
They are standing in a corner and probably feel ashamed.

They are actually haggling. Not with money or food, because they don't have anything.
By rejecting some of your free food, they can regain some of their status.

Didn't you make a similiar thread in the past regarding how you gave food to the church and the people that received your donation were ungrateful? If I were you, I would stop giving to that fucking church. If your donations are not good enough then let the fucking bastards starve to death.
