Ok, I'm calling bullsh!t on this...
The following is posted in the Trivia bits under Kubrick's biography page here:
Abigail Rosen, who co-starred with Viva in Andy Warhol's Tub Girls (1967), was the first door lady at Max's Kansas City, a nightclub in New York City. She claims she had the honor of throwing Kubrick out of the club. "At first Mickey [Ruskin] hired me as the coat-check girl, but it was on the second floor and we were schlepping coats from downstairs to upstairs, and taking them back down where the people wanted to leave. It was not a good plan, besides which people would go up and steal coats. So we abandoned the whole idea and I became the door lady with Bob Russell. The embarrassing times were when Mickey asked us to kick somebody out. The philosophy behind it was that no one would beat on or abuse a woman. I was asked one night to kick Stanley Kubrick out. He was drunk and obnoxious and neither Mickey or I knew who he was. I said, 'Sir, I think it's time for you to leave now, you're not going to be happy here.' And he left. Then Mickey found out the next day who we had kicked out, and he yelled at me for not recognizing him. 'That's why I have you here,' he said, 'you're supposed to know who these people are.'".
This club didn't even open until December of 1965, and 2001 began principal photography that same month in London, so I seriously doubt Kubrick attended it's opening in NYC.
And then, Stanley Kubrick "drunk and obnoxious?" Just not seeing that.
It appears that this Abigail Rosen person obviously took a lot of drugs in her day.
