1. After disagreeing with a line call, the player looks directly at the line umpire and clearly says, "F*ck you."
DEFAULT. Say all you want under your breath or in another direction but look at me...and you get "The Thumb." That was my "Rule of Thumb" when I umpired collegiate intramural softball (fraternity division, no less ).
2. Same situation, only this time, not looking directly at the line umpire says, "call it out you f**ker."
Eh. Part of the game. Let it ride. Merely a Code Violation (if that).
3. After disagreeing with a decision by the chair umpire, the player, from the baseline, hits a ball hard, clearly aiming at the chair umpire, but the ball misses the umpire.
DEFAULT. Outa there. Physical retaliation has no part in the sport.
4. After a point, a player accidentally hits a ball very hard and recklessly and the ball hits a ballboy on the shin. The ballboy is not injured and is kind of laughing about it after it happens.
No biggie, IMHO. Part-n-parcel of the job.
5. Same thing, only this time it hits the ball boy in the stomach, and the kid is bent over obviously hurt badly.
Still...part of the job.
6. A player takes a bathroom break escorted by a line umpire. The line umpire comes to you after the bathroom break and tells you that the player's coach met him outside the court and was giving the player instruction. After the line umpire told the coach he couldn't to that, the coach immediately stopped.
DEFAULT. They KNOW better. Get 'em outa there.
7. Same situation, only this time, after the line umpire told the coach he couldn't do that, the coach continued to give instruction.
DEFAULT. Same as above. No excuses. G-O-N-E.
8. A player takes a bathroom break, escorted by a line umpire. The line umpire reports to you that the player went into the locker room, lied down on a bench for 2 minutes, then got up, went to the sink and rinsed his face off, then came back to the court.
Been there. Done That (except sitting on the potty in an air conditioned facility) Just part of the game, as long as it's done within the "usual" time...although the player should be smarter about it.
