The correct answer is:
The score should be “15-30,” and the server should get another first serve.
From The Code, Item 32:
According to Item 32, when a dispute occurs over the score, the players should first “count all points and games agreed upon by the players and replay only disputed points or games.” So long as both teams agree that Carmen’s team had won the previous point, then the score should be “15-30,” regardless of the score that was called by the server. While Carmen’s team could argue that the server should only get a second serve since the delay was caused by the server’s error (The Code, Item 30), in most friendly situations, a first serve is appropriate in the name of good sportsmanship.
