Personally, I'd just suck it up and move on. And if the guy comes back later, I'd politely decline to do any more - the way he handled you clearly isn't how you (reasonably) expected to be treated, and those early interactions with clients are almost always an accurate forecast of how any working relationship would continue.

So, walk/move on and don't give yourself a hard time about it. Yep, you did some work for someone who seems to have stiffed you. It happens, but don't worry too much about it -- it's all part of the learning curve.
