This post sounded better than the original article. Not that fact that he brought lunch made you like him, but that he was a pretty amiable guy to begin with, and that he found his happiness by buying lunch for people he liked for a shared experience. The original post made it sound like one can be easily brought with a quick lunch. I personally am wary of having just any stranger do me favors because then I'd feel obligated when they ask me for something. This is how people end up buying entire rugs when they go to have 'just a drink of tea'. But yes, I understand this wasn't the situation you were talking about.
