I agree, Gordon can handle names being thrown at him. I doubt he would have a problem with confrontation at all. He knew they were far beyond hope, so called it a day.
We watched the episode with our jaws on the floor for most of the hour. These two people were truly nuts. I loved how livid Gordon was when he found out Samy was taking all of the waitstaff's tips. Telling the customers that and shutting down Samy's blustering was awesome, as was shoving some cash into the server's hand when he walked out the first night.
Apparently the social media fall out is epic, as we can see from the link above. My husband says someone on Reddit posted that a cop friend felt pretty strongly the restaurant is nothing more than a money laundering site. I can believe that. Samy is scary, and Amy is off the wall crazy. Seriously nuts.
The scary part is, they will probably get their own reality show out of it.
