Conclusion
The ITTF Laws of Table Tennis are in place to help ensure that everyone gets a fair deal during their matches. If your opponent is accidentally or intentionally breaking the rules, then you are no longer getting a fair go, and you should feel justified in seeking to correct the matter. But do it as politely, tactfully and calmly as you possibly can, and you will have better chances of success. Being right does not give you the right to be obnoxious about it. Attempt to resolve the matter with grace first, and if that is impossible then escalate the issue to the referee or competition directors. If you are in a social setting and you feel the matter is important enough to warrant action, try to get an impartial ruling from a qualified official, or get a peer group together to discuss the situation and try to come up with a fair solution.Remember that there will always be the occasional hard case who will refuse to correct his behavior, but in a social setting he can be avoided or influenced by peer group pressure, and in a competition environment he is subject to the decisions made by the umpire, referee, or Tournament Committee.
