I do not stand on the service line to return serves. I will step if I need to block a serve back if it is a strong serve. I do not worry about out wide serves too much (i am very quick) and like out wide serves. If someone is stupid enough to keep going out wide to me, I will step in one step to help myself out and make my return even better.
I do not care if a server serves into me or a ball is hit at me and happens to hit me. Just part of the game.
