If the foot faulting continues, the player may attempt to locate an official. If no official is available, the player may call flagrant foot faults. Compliance with the foot fault rule is very much a function of a player's personal honor system. The plea that he should not be penalized because he only just touched the line and did not rush the net is not acceptable. Habitual foot faulting, whether intentional or careless, is just as surely cheating as is making a deliberate bad line call.
Service calls in doubles .
In doubles the receiver's partner should call the service line, and the receiver should call the sideline and the center service line. Nonetheless, either partner may call a ball that he clearly sees. Service calls by serving team. Neither the server nor his partner shall 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. But the server and his partner shall call out any second serve that either of them clearly sees out.
