I disagree. I think player B could have been correct. Scooping the ball with the cue is a foul if it jumps up, so I don't see why he doesn't have a right to clarification. If he was purposefully prolonging the discussion then it would have been sharking, but it sounds like their could have been legitimate reason to question things, or at least that he thought he did.
Was there an open table nearby? Set up the exact same shot he is on and practice it 20 times while "player B" is arguing with the league official. Or pull some balls out of the pocket on your table and hit them while B argues.
Use it to your benefit.
That's actually a foul in BCA, abaha
How in the **** can you scoop a ball when using a bridge? you have to have a very low, level cue to scoopit, not hitting down on it from a bridge?
