I play tennis in the UK in adult leagues and I always play by the code. http://www.usta.com/Active/The-Rule...e_The_Players_Guide_for_Unofficiated_Matches/ Recently I have been getting angry more and more often because other players (including doubles partners) don't play by the same rules - breaking the code all the time in every match. How do other players get around this? Should I tell my doubles partner he is breaking the code during a match? What is the best way to deal with this?
