When a coach has reached his limit with me regarding complaining I just say, "I've heard/had enough." He's grown enough to understand what comes next.

If a coach is unhappy about a specific call and hasn't been a PITA I generally just say, "I got your point let's move on." He's grown enough here as well to understand what comes next.

When working with less experienced officials who are taking a beating I generally tell my partner that the next time the coach says something just tell him you've had enough. If it's a stoppage in play also tell me that you have warned to coach. I also, if I think that my partner has taken enough abuse for the crew, at the first sign the coach is going to whine to me, he gets his warning. Crap from a coach is accumulated as a crew IMO, and it shouldn't be individually earned.
