He knew that I knew and made no attempt to touch the one-ball again.
He asked Rob to rack one again. Rob did it without complaint.
I'm guessing someone informed Ignacio he should ask for another rack instead of touching a ball himself.
I played one of the current "superstars" in a tournament. After I racked he touched the one-ball, I looked at him and said "I'd appreciate it if you don't touch the one-ball with your hand."
The very next rack he did it again and my tone changed and so did my eye contact. I lowered my voice and said again, more sternly this time "I know what you're doing, DO NOT touch the one-ball again!!!"
He knew that I knew and made no attempt to touch the one-ball again.
I can't blame them for trying, but I do blame them for continuing after a warning. We had referees at a lot of our major events, besides it would have not been pleasant for a player to try to do that to Buddy Hall, Wade Crane or Allen Hopkins.
