Some people are more than happy to help you ...but only if it costs them nothing. Learn who will gladly help you as long as its free, and do not have as good of oppinion of them.
2 Samuel 24:24
But the king replied to Araunah, "No, I insist on paying you for it. I will not sacrifice to the LORD my God burnt offerings that cost me nothing." So David bought the threshing floor and the oxen and paid fifty shekels of silver for them.
