If you tell them 1 and they really have none, they have a good reason to gripe when they take it, find out they have none, then get a T. If you're wrong when you tell them 0, then there really is no problem. It can be investigated and corrected with no consequence.

There could still be a problem. (name ANYTHING we do that has no potential for a problem) If you say he has none when he really has one, then his player gets trapped and turns the ball over and the coach would have called a timeout, that could be (rightfully) perceived by the coach as a problem.
