I get it. It is not about the money, it is about the consideration. You get this great source for scrap that cost you nothing but time and yes, he is happy to have it gone at no cost to him. He smiles at the clean yard. However, you return with a few dollars (maybe even only lunch money) for him and you have a supply for life, He will call you again and again because it is not about the amount of money you give him, it is about the consideration you show him for giving you the scrap.
