Start first serve with two balls - When you begin your first serve, have a second ball ready in case of fault. If the first serve is a fault, you'll be prepared to initiate the second serve without delay. Retrieving a ball between the first and second serves disrupts the pace of the point. Distant balls should be retrieved at the end of a game.Avoid foot faults - It is a foot fault when a foot just touches the line, even when the player does not follow the serve to the net.
Calling foot faults - The receiver may call foot faults only after all reasonable efforts, such as warning the server, have failed and the foot fault is so flagrant as to be clearly perceptible from the receiver’s side.
Service calls by server - The server shall not make a fault call on the first service even if they think it is out because the receiver may be giving the server the benefit of the doubt. There is one exception. If the receiver plays a first service that is a fault and does not put the return in play, the server may make the fault call. The server shall call out any second serve that they clearly see is out.
Service let calls - Any player may call a service let. The call shall be made before the return of serve goes out of play or is hit by the server. If the serve is an apparent or near ace, any let shall be called promptly.
Obvious faults - A player shall not put into play or hit over the net an obvious fault. To do so constitutes rudeness and may even be a form of gamesmanship. On the other hand, if a player does not call a serve a fault and gives the opponent the benefit of a close call, the server is not entitled to replay the point.
Receiver readiness - The receiver shall play to the reasonable pace of the server. The receiver should make no effort to return a serve when the receiver is not ready. If a player attempts to return a serve (even if it is a “quick” serve), then the receiver is presumed to be ready.
Delays during service - When the server’s second service motion is interrupted by a ball coming onto the court, the server is entitled to two serves. When there is a delay between the first and second serves:
• The server gets one serve if the server was the cause of the delay;
• The server gets two serves if the delay was caused by the receiver or if there was outside interference.
The time it takes to clear a ball that comes onto the court between the first and second serves is not considered sufficient time to warrant the server receiving two serves unless this time is so prolonged as to constitute an interruption. The receiver is the judge of whether the delay is sufficiently prolonged to justify giving the server two serves.
