ejection for asst coach - how many free throws?

[Oz Referee]

I had a funny sitch a few years ago.

About 90 seconds to go in a tied game, probably the equivalent of a High School game in the US.

Assitant Coach is complaining non-stop after a charge is called on the team's star player (who happens to be his son) resulting in said player fouling out. So I T up the Asst Coach. Asst Coach continues whining and doesn't get the hint, so I toss him - without calling another T. He then complains that I can't eject him as he only has one technical foul so.........he gets his second.

Opposing team shoots 4 free throws plus gets the ball back, they hit 3/4 and score a 2-pointer on the next play. They end up winning the game by 3.

After the game the Head Coach walks towards me. I think "oh god, here we go". He sticks his hand out to shake mine and says "thank you so much for doing that, I've been trying to get rid of that a$$ for years, but since his kid is out best player the association always gives him the Assistant Coach job"

All round was a bizarre experience.
