Joe stepped in to Back Up Gordon Ramsay Against a Heated Contestant

"The contestant disagreed with Gordon Ramsay’s comment that his cake was too sweet, insisting that it wasn’t sweet at all and that Gordon just had a different taste. When he also refused to accept Graham’s opinion, Joe stepped in to back up Gordon and told the contestant to stop being disrespectful and take responsibility for his mistakes."
