Gordon Ramsay, a rich and famous chef, years ago hit the reality TV circuit by acting as a consultant to failing restaurants.
Two things strike me about this series.
First, these restaurant owners and employees, despite having so many problems when they agree to be one of these shows that they are on the verge of bankruptcy, have the gall to actually argue with his suggestions for becoming successful.
Second, I often wonder why, after seeing one of these shows, I ever go to eat at a restaurant again! LOL Interesting in the manner that makes people slow down to view the details of a car wreck, Nightmares often provides an uplifting story of a group of people getting it together to run their business properly for the very first time. Sadly, there are those that are so stubborn, and/or so inept, that they fail despite Gordon's intervention.
There is a lot of bad language and bad food, so this is not for small children. If you run a business of ANY type, you can learn real lessons for success from these shows.
