It's BS, this guy is an idiot cartoonist who fancies himself a genius despite his failed restaurant and various public shamings for gross behavior.
He's failed at a lot of things. But yes, he went into business with an experienced restauranteur and opened a couple of restaurants. Then as they started to dip, he tried to "dilbertize" them which naturally did not work.
Beyond that, he's just a sexist, narcissistic, asshole

Nobody should listen to anything he says.
