if you are so picky just ask him to touch the cue ball with his tip.
then maybe if he is stuck and ready to lose all his cash he may just quit after that game.
then you can be proud that you enforced the rules exactly even when it makes no difference.
It made no difference. I didn't dwell on it. Just told him
that was different, that usually player's at least make a
legal intentional foul, which made us both laugh. Later,
after I was home and lying awake in bed, I thought
about it and wanted to see what others thought.
