Dull people are more interesting than interesting people, generally.
These fellers aren't putting on a phlegmatic act, as far as I can tell. They might be mugging for the camera for all we know; catch them on a regular day and they'd be cigar store Indians.
Businesses, even businesses that are interesting to people who aren't customers like these boatbuilders, need sober and industrious people to take risks and stick to business. I grow weary of lamebrain pitchmen. Make something people want, and make money at it, and don't fold your tent in the night five minutes after your first profit. Then you're a businessman.
