Amy and Samy Bouzaglatell, owners of Amy's Baking Co., appeared on Friday night's episode of the show, hosted by celebrity chef Gordon Ramsay, KSAZ-TV, Phoenix, reported.
The Bouzaglatells were seen on the show fighting in the kitchen staff, yelling at customers and taking their servers' tips.
"After 100 kitchen nightmares, I met two owners I could not help, it is because they are incapable of listening," said Ramsay after walking out on the Bouzaglatells.
The Bouzaglatells say the show sensationalized the situation and that they don't yell at customers and that customers featured on the show exaggerated problems.
Some people say they still won't support the restaurant, the report said.
"I wouldn't want to go any place and spend my money there if they treat the staff that way, and to also keep the tips, who does that?" said Marv Rousselow, who saw the episode.
Another person wrote simply "you are evil" on the Yelp page for Amy's Baking Co. The restaurant has received one and half stars out of five on Yelp.
The Bouzaglatells said they have also received death threats.
Yet, some people like the restaurant.
"I've been back 10 or 11 times, I love it, the second time today," said patron Debbie Hilcove.
