I play club mixed doubles. I have the following questions: 1) Once, while at the net and my partner serving, a ball rolled back from the wall behind my partner, onto the court, about three feet away (her box). She refused to serve. I finally looked around and she was glaring at me, wanting me to get the ball away from her, and eventually insisted it was my responsibility, as she was serving, although it was much closer to her than me. I thought this a needless waste of time, and she should police her own court. Thoughts? 2) Yesterday, I was lectured by another partner, who was receiving a serve (I again at net) that it was my responsibility to tell him if the first ball served was rolling back up behind him. He claims he needs to concentrate on the return. I say it's his box, and his job. Who is right?
