Kindly define why declining a request from the cabin crew is deliberately interfering with the execution of their duty?
They ask politely, you decline politely, how have you interfered?
If you think this is breaching the ANO, you are misguided.
If the captain decides that the blinds must be closed and makes it a command, then that is an entirely different matter, but in over 1,000 flights I have never witnessed that circumstance.
