It is quite possible that he simply overestimated what you had and after cherry picking out the best stuff he just bailed with what he had. I had the same thing happen to me with stuff I was just giving away. It took 3 different people to get a couple hundred CMUs and a stack of rebar out of here. (2 guys who wanted block/rebar and a scrapper) I still have a stack of pallets to get rid of.
