... to all my floor captains is whenever I need (not when they might want) a clarification, the are to approach the official after a dead ball calmly, maintain eye contact, ask the question, listen to the answer given, thank them politely, immediately turn around and come back to me with the response. Floor captains are not to debate or insert their opinion during this interaction.

I use the concept of floor captains only for this purpose.

I've NEVER had a single problem with this approach. In fact, the officials often tell me that my players are much more composed than I am - hate it when they're right.
