[JAdams]

If a coach is civil and under control, I'll always talk to him/her...for a few seconds. I'll tell them what I saw and how I interpreted it, especially if a rule is involved. Seems to me this is simply good commication skills. I know that coaches often genuinely want to know what I had on the play.

I agree with the posts above this one, however, that I won't do it the entire game and I will be very reluctant to go over and talk to a howling monkey.
