Very cool! I've encountered the same thing at my yard, and have actually become good buddies with the owner. I'll go out and help him and his boys pick up a big load, and he'll throw me leads on pick-ups all the time. It's absolutely great to interact with the yard owner (assuming it's a smaller yard).
Oh and bring them pizza/beer/water/meat...or something they can consume one day, it's a good gesture on your end and little favors like that can pay off in very big ways!
