Maybe they don’t like liars. Keep in mind that the network broadcasted his claims, and find themselves embarrassed about it. I just mentioned Rachel Ray—she never claims to be a chef at all, just a practical and impatient cook—and she’s hit the big time.
The Food Network has a reputation (goodwill) to be concerned about, yes. And if this guy is a talented chef, he’ll land on his feet anyway . . . despite being a liar.
