So in my match last night, I was accused of cheating because I did NOT call the ball out when my opponent's serve hit the line. The serve hit the back half of the service line, I just barely got the return back, and my partner and I won the point two shots later. Despite the fact that the ball took a horrendous bounce (hence, my weak return) and made a hollow sound (two signs on our crappy carpet courts that the ball hit the line), and despite that fact that there was a big black mark on the line, the opponent at the net starts accusing me of making a bad call, as if hitting a weak return off a horrendous bounce is somehow in my favor. He started pointing to a faded mark over on the sideline that itself was only a fraction beyond the service line, even though it was several inches over from where the ball actually landed. After implied accusations and threats of retribution, I told them both that they know perfectly well that, if I had called it out before they contrived to lose the point, they would have been fuming, so they can't have it both ways. Has anyone else "cheated" someone by calling the ball in?
