But, then, snooker players will call such fouls on themselves when even the camera doesn't pick it up.
Interestingly, one thing I have noticed about cultural differences playing the game where I am now...
- Europeans will always call the foul on themselves, often at their own detriment, and often even being berated by their team mates for doing so... Usually picking the ball up and giving it to the opponent as soon as they foul.
- Americans want you to call the foul on them, otherwise they say nothing, and see it as the other player, or referees job to do this.
- Chinese nudge the ball, look at you and laugh, and put it back and carry on
This is what I have noticed in team based league games, or at the bar - in fact, two or three times I have seen Americans yell at their team mates regarding this.
In the few tournament I have played, the same applies - except for Chinese now follow the exact letter of the rules, and take a more European approach to the rules, and call the foul on themselves. Americans, I have noted, still say nothing and want you to call them out.
This is not a flippant observation, but one grounded in many experiences in my short time playing the game here against international opposition (note Japanese, Korean friends have tended to take the more European approach, and Phillipino friends, the more American approach - though I have far less experience against people from these countries - maybe 10 or so players from each).
