My guy, I can bring a trailer load of parts to him, he always says $40 I always come back with, that is too cheap and give him extra.
One time I had him do a rail-road conductor stand it was most likely from around WWII, it was heavily coated with multi-layers of paint.
I also said powder coat it, since I planned on actually using it.
He called me said, it was done, come get it, but he was not going to be there.
I asked how much did I owe him, he said nothing, free its sitting on his roll back.
Ever since then, whatever price he gives me, I just hand him 2X.
