Sheez. I was playing with a particular partner who always returns Obviously Out balls, always. She was receiving. The server mishit the first serve so that it bounced on her side of the court and then bounced over the net. My partner returned that ball. And this is a woman I have told in the past to stop returning Obviously Out balls.
Cindy, do you mean balls that people call out but hit back over the net anyway? Or serves you think are out but the opponent is playing them and looking for two bites at the apple?
