That sounds a bit harsh, doesn't it? He sounds like a decent enough likable guy.
You can tell from the video he isn't rich, or anything like that, so he's just trying to make a basic living from doing what he love and what he's good at.
He didn't try to sell you up to anything in this video... The opposite of that, in fact.
So at least in this instance, this response wasn't warranted. Give him some break.
You can't put yourself in his shoes.
I don't think you quite understood what garpike said, also the video is quite old, he has changed.
