If it rains before the match starts, the whole match must be re-scheduled
If it rains during the match... either player may decide to call a halt to the match, but the match must still be completed. Matches
should be re-started with whatever the score was when play stopped. Players must share any additional court fee. If re-scheduling
becomes impossible, the score can be reported as final if both parties agree
If a player retires injured, he or she loses the match - it cannot be re-played.
If a player does not turn up at the agreed time, or is more than half an hour late, he or she forfeits the match.
If one or other player decides they don't want to play a match they can not offer a walkover to the other. That is, for
points to be awarded a match has to be played.
