There are rules to this game. Regardless of whether or not the line judge was seriously hurt, injured, the point is that there are rules to the game, and if a player violates the rules, then they pay the consequences. What is so difficult about that to understand? Djoker screwed up. Literally, he screwed up, unintentionally or otherwise; therefore, he has to pay the penalty. It’s the rules of the game. Folks may not like it, but that’s the way it is.
My daughter, tennis player, had this nasty habit, if she was unhappy about a shot, of saying “cheese and rice”, which always infuriated me and she knew better. She was playing In the Division One, Ohio state high school championships. She was in the quarters and it was close. She missed a shot and screams “cheese and rice”. The chair judge penalized her a point for language, which was a tie breaker point for the match. She lost, her HS coach argued with the judge saying she did not say “JC”. I said, tough luck, off the court. I had warned her many times, her fault and tough lesson.
