I know "reality" shows are scripted in everything but name, but I don't think you could have made up that vapid, narcissistic "chef," her ineffective, enabling sugar-daddy husband, and their soulless vanity project of a restaurant.
If you go back and read the negative Yelp reviews
from before the Kitchen Nightmares
episode, it's all there — the food, the rudeness on the part of Samy and Amy. What's more amazing is that they didn't even try to be on their best behavior for the cameras. Two examples of them lashing out at their critics:
Joel L., 8/1/10
(the one that started it all)
Stephen C., 11/17/12
I imagine it's too late for these people to learn, you never go full retard.
