I wasn't there, I don't know if that shyt is true or not.
What I do know for fact is that Punk has been constantly disrespecting Hangman for a year now. He's had a year to pull up on him.
Punk also said he was afraid Hangman was going to shoot on him during their title match to ESPN & texted Hangman an apology a few weeks ago after the whole post-match heat seeking promo. The fact that they're communicating to each other via text makes me believe their supposed beef is blown out of proportion by fans.
I don't think Hangman wants to work with Punk because of everything that's happened. It's not worth it to him. Hangman's been out of the title picture for over a year, but he's still one of the most over guys on the roster. That's why I compared it to the Triple H/Punk thing. Punk is angling for it, but Hangman is just no selling it.
