Nah, you feel everything the cue does. There's no way he didn't "feel it" but without seeing the 9 ball move, he probably didn't recognize it as a foul. I can assure you he "felt" it, I'm not saying he did something nefarious, I am saying he felt it, but with the small distance the ball "tipped" he may not have recognized it, what i can assure you is that he felt it. Hope somebody asks him, if he's as honest as we all believe him to be, he will admit he felt it.
When this happens, you all owe us apologies
