[Junker]

He questions the junior varsity coach about this, who replies that the varsity players are also warming up with the junior varsity team, as they "always" do. The referee requests that the varsity players leave the court, after which the varsity coach interjects by saying that the varsity players "always" do this, but he pulls his varsity players off the court.

I don't know, sounds a bit confrontational to me. Why have this be the first conversation of the night with the coach? If it is always happening, you begin the game by looking like an OOO and you aren't on great terms to begin with. I'd ignore it and talk to my association. If it is ignored every time, I'll be ignoring it as well.
