Never saw this before

[just another ref]

Tonight, GV, I was a spectator. V head coach got her second T early in the second half, down by 10 or so. She walked across the court and left without further incident. Her team clawed back, and finally went ahead by one with 12-15 seconds left on a steal and a layup. Big girl for H missed a wide open potential game winner from 2 feet at the buzzer. V erupted into a wild celebration in the center of the court. Officials were almost out the door........and then they stopped. There was the HC, in the middle of the celebration. They came back. One approached the group, and they exchanged words. I was told afterward it went something like this:

"Coach, you can't be in here."

"I'm just celebrating with my team."

Whatever it was, it wasn't the answer he was looking for. He gave a series of quick blasts on the whistle stepped over in front of the table, and made the T sign. She was escorted out again. Home made one of two, the game went to overtime, and the visitors lost.

If you see this coach come back in, what do you do?

1. Immediate T
2. Go to her and give her the opportunity to leave again
3. Keep walking
