No, it was a house show in Nassau right around Summerslam. Vader and Cornette have both confirmed this in interviews. Vader was being stiff, Shawn threatened him, and he cried. The Summerslam thing only doubles down on my point that Vader shoulda beat his assThe peak of the situation between them wasn't about Vader being stiff. Does the OP know this? It's because Vader missed a spot at Summerslam and Shawn threw a temper tantrum.
People shyt on Shawn for it for the same reason people shyt on Randy for the Kofi situation. Someone made a genuine mistake, owned up to it, but a petulant crybaby held them down for it for as long as they could.
