Making Coach sit

[Refk]

Working with new partner last night and HC getting a bit unruly with him, partner talks with HC and he sits down. Partner comes to me at next timeout and says he told the coach to sit down for the rest of the game or he would be ejected.

Question: Is this a method one should use or stick to more conventional method --- warn , T , etc...

I normally warn coach then if needed administer T (which seatbelts him in my area ) never really told coach to "sit down or else". I have told them I've heard enough but never "sit them down" ??

BTW my partner was great to work with and the coach did settle down.

Thanks
