(Reposting my comments on this from TNZ)
I've never seen the show, but after the reaction to it here and on the rest of the internets, I had to check it out on YouTube
and read the Yelp and Facebook drama.
God, what a train wreck. It's amazing that this insane couple is still in business at all between verbally and physically assaulting customers, making terrible tasting or uncooked to the point of being dangerous food, stealing their servers tips, their inability to take any criticism or disagreement, and their extremely high turnover rate due to mistreating their employees.
The negative reviews, which are only going to get worse now that the show's aired, will hopefully put the final nail in the coffin. Normally I wouldn't root for a small business to fail, especially not a restaurant since they fail so often as it is, but this couple has no business being anyone's bosses or dealing with customers.
The wife seems to have some talent at baking cakes and pastries and putting them in a pleasing display, so maybe she should try working for someone else's bakery and learning to take criticism a bit, but she just seems too far gone and arrogant to adapt. And the husband (Mr. "You're not gangster, I am gangster!") should just stay away from dealing with the public altogether before he beats someone up or worse.
