I handled this correctly as far as I can see. But I will see what you guys think I should have done or should do in the future.
A1 gets fouled in A's backcourt by B1. B1 who is visibly upset complains outwardly and gets called for a T as well. A1 is selected by A's coach to shoot the T FTs. A1 misses the first, then makes the second FT. Then the scorers table tells the officials, that the first common foul by B1 put A in the bonus.
What do you do now? I will tell you what I did after a few responses.
