Me (to Coach): "[My Name]. Pleasure to meet you Coach. Best wishes to your team." Done and gone!
I try my best to stay away from anything a coach may use against me later.
Had a coach tell one of my co-officials something pretty funny one time . . .
Partner: "Good luck to you coach."
Coach: "With you on the floor, we're going to need it!"
Turned out just fine, and the game was great.
