Make the coach take a time out?

[rsl]

In a freshman game, A1 is dribbling right in front of his own bench.
A1 loses control and A1 and B1 scramble for the ball. A's coach
immediately starts yelling for a time out. There is no player control,
so I hold my whistle. After a few seconds, A1 and B1 tie up and
I whistle for a jump ball.

Now the question. Of course, A's coach no longer wants the time
out- he only called for it to keep possession. Do I make him take the
time out anyway?

I let him off the hook, but B's coach asked me why there was no
time out.
