When filming Dr. Wilkes at the bar, Dr. Wilkes was doing pushups against the bar and dancing around. Producers were unsatisfied with the level of extremity, so told him to make disreputable comments to women in the bar.
In a later interview before the show, the producer said that in order to "get the show," Dr. Wilkes had to make offensive comments about women. He was assured that the comments wouldn't be seen by the public and Jon Taffer would be the only one seeing them. The producer asked graphic questions about women's parts, and when Dr. Wilkes' responses weren't graphic enough, the producer coached him to make his responses more graphic, and to "say it like this."
Producers told Dr. Wilkes that Nicole Taffer would be coming into the bar to help with the casting tapes, and when she arrived with a friend, the producers texted Dr. Wilkes to stay away until they give him a cue to approach them.
When he got the cue, he approached them and talked to them, while the producers watched from a control room. The producers weren't satisfied so texted Dr. Wilkes to "Hit on [Mrs. Taffer] hardcore!!"
While watching the scene from an SUV, Jon Taffer allegedly called the control room to tell them to have a drink near the spot where he intended to confront Dr. Wilkes, so he could throw it in his face. He allegedly said to a colleague, "Now I'm going to show you why my show is Number One."
Dr. Wilkes then claimed that Jon Taffer came in to confront him, showed him footage of his audition tapes where he insulted the way Jon dressed. Jon then grabbed the drink in his hand, threw it in his face and smashed the cup in his face. Jon then spit in his face and tore off his shirt so violently that buttons ripped off his shirt. Jon then picked up the second drink that was planted and threw it in Dr. Wilkes face. After that, Jon swung at Dr. Wilkes' head with his electronic tablet, and turned to go towards his coat. Dr. Wilkes thought he was going for a weapon so tried to restrain him, and was punched in his left jaw by Jon Taffer. Jon Taffer began hyperventilating and collapsed on the floor, and the entire attack was caught on camera.
As a result of this attack, Dr. Wilkes suffers from emotional distress and things such as migraines, nausea, vomiting, night terrors, crying spells, severe depression, and anxiety attacks.
