I suppose I can't speak for everybody here, but my clients pay me for more than just coding. They pay me for my experience, and knowledge of what works and what doesn't. Maybe I'm weird like that?

Oh and I would never suggest laughing at a client, or ridiculing them in any way. As a consultant, agency, or freelance whachamacallit, the ability to talk to a client is nearly as important as the work you can produce. I've spent hours on the phone discussing projects with people, for free, to land the next gig. I've been introduced to new technologies that I might not have discovered otherwise as a result of listening to them. At the same time I've had to tell quite a few that certain concepts of theirs are a bad idea and why. I've never lost any clients from doing this either.

The guy isn't an egotistical ass. He's just another guy who has made an exaggeration out of the kind of client we've all had to deal with, and fear the most. Take it for what it is, a good clean joke.
