I know people like that.
In the case I'm thinking of, the player honestly believes it is bad to hit the ball *to* the other player. The thinking is that this will train your brain to hit the ball to the other player in a match.
This means they consider it a waste of time to hit the ball anywhere you can reach it, ever. Good luck constructing a mutually beneficial drill with this player. Good luck trying to groove your technique and work on consistency.
