as I said repeatedly, I do not care, that text is not a law, it is a guideline.My preferred approach, in RPGing, to the possibility of being caught by surprise, is dice rolls. But D&D uses a mixture of dice rolls and fiat authority. The Noble ability is fiat authority, and the flavour text for it underpins that: the player knows the ways of their own social class. If the player declares use of the ability, it's too late for the GM to now retroactively tell them about stuff they knew that would explain why the action can't be declared.
If there are reasons to not grant an audience then you knowing ‘how to fill out the form’ still gets your application denied.
No one said you cannot ask for an audience (that is declaring the action), you simply do not get one.
