3 part question 2 of 3

[wbrown]

We are playing on the side court as described in part 1 of 3. The coach continues to walk out on the court to coach his kids. During a free throw at the opposite end he is out on the court about ten feet talking to two of his player. My next time up court I ask the coach to stay off the court and his response was “Is that what you are concerned about, you should be more concerned about the game”. I wanted to give him a T right there but he caught me so off guard with his comment I just let it go. How would you have addressed the coach?
