Mystery Diners - Season 5 Episode 2 Fired Up

The owner of Looney's BBQ in San Leandro, California asks Charles to investigate his staff when he hears that some of them are pranking customers with the restaurant's Devil's XXX hot sauce. He is shown why by the Mystery Diners when his waiter Matt and manager had been behind the pranks. The manager is disciplined by the owner and asked to be more friendly to the staff while Matt is fired. In his exit interview, Matt stated that he didn't regret his actions in giving some of the customers the XXX hot sauce because they were acting bad around him and he believed they deserved it. The narrator revealed that Matt had found employment elsewhere. The manager has adopted a more friendly approach and no longer hazes the staff.
