Taking signs off the rubber.

[rbmartin]

Last Night. JV double header (FED rules). Game 2. 6th inning with starting pitcher still in game. Runners on 2nd & 3rd. I was at "C" position. Defensive coach (who had already proven himself to be a rat a couple of times) starts complaining (from the dugout) that the pitcher was taking signs off the rubber (not delaying or quick pitching or anything like that). He says I should call a balk. I said "coach, how do you know when he's taking his signs? Just keep quiet and lets play ball." I know 6-1-1 says "shall take his sign from the catcher with his pivot foot in contact with the pitchers plate" but specifies no penalty.

I'm sure this question has been discussed several times but I have a few questions:
1) Other than saying "don't do that", how should I handle the pitcher?
2) have any of you guys ever seen this infraction (if you could call it that) called?
3) What would you say to the rat/coach in the dugout?
