Hi! I was at a series of local cups recently and I asked an opponent if they would mind using a die instead of a coin. While that player ignored my question, thats his right I guess to do so if its a randomizer (which coins are). Anyhow at the next cup I asked the same player before the match as well (I typically ask if a player can use their dice instead of coins before a match). That player informed me that it was against the rules for someone to ask for a person to use a different randomizer. I was curious if that was actually a rule and I asked the TO at that event if that it was indeed true and if you could get a penalty/warning/whatever in that case for asking an opponent if they could use a different randomizer. The TO told me that it is indeed against the rules to ask a player to use a different randomizer. The TO wasn't aware though what the penalty would/could be in a situation where it was needed though. My questions are based on this scenario. I looked up in the rules and didn't see anything against just asking if a player would mind using a different randomizer in the rules, what specific violation of the rules would this be? Also what would the specific penalty be for asking this question?
