What I was trying to get across in my last post was that most of the people running these businesses (for example the president of the toy company that produced Aero Flix) don't come off as the sort to voluntarily say "yes, I am over my head".
I think it was the butchers where it was the office manager who actually did the submission and I recall in a few of these shows (and kitchen nightmares too) it wasn't always the owner asking for help but those affected by the failures.
In some situations the owner thinks the problem is elsewhere: everything they are doing is perfect (based on personality) but they are still losing money, help me find out why!
Also, I'm sure there is some correlation between a severely failing business and the personality of the owner.
