Server

[Hawkeyes]

Doesn't this depend on the level of play and the official's discretion since "the service" never began? The officials can stop the match for any reason.

I suppose that if a player dropped the ball, it crossed the line without touching the foot, I'd likely call for a replay and not a reserve.

However, it would be interesting if the servers teammate picked up the ball, tossed it back to them, and it was served within five seconds, or if the player crossed the end line, retrieved the ball, and returned to the service area for a legal serve, all within five seconds...whew,
It seems like a nightmare that is avoided by stopping and permitting a replay or reserve.

Option C seems like I'd be breaking into jail.
