When I play in my league, there's almost always one example of violating the rules per match. For example these things happened: 1. My partner was serving. He hit his first serve into the net and as he was preparing for the second serve, a ball from another court rolled over. My partner stopped, got the bal, and hit it back to the other players. No one even considered if he should be given a first serve. I thought about saying that it should be a first serve, but I wasn't sure if it was my call. 2. We were engaged in a long, drawn out point. Right when one of my opponents was hitting a volley way long a ball from the other side (we had an especially shanky group next to us) bounced on to the court. However, the team didn't notice the ball! After the point they saw the extra ball and then said that we should play a let. I once again knew that this was wrong. You have to call a hindrance immediately, not see it later and then say "hey! that was a hindrance!" 3. Finally, I hit a serve, that would have been an ace. The returned said "oh! Nice serve" his partner then said "No, it was definitely out." The returner then said "Oh, he called it out. Second serve." I mean c'mon! I don't usually argue because these matches are basically just for fun, but after writing them all out I'm realizing how irritating it is! I think I'm going to start calling them out.
