Nope... I don't ask permission when time comes to eat... I inform the captain prior to t/o that my plan is to get my meal immediately after we get to cruise, during X break, or in the bunk... I'm not asking permission. If the captain (small C) says nope then I'd be calling the FODM and telling him/her that we have an issue and can't depart until solved. Bottom line, I'm willing to follow guidance on how the flight will operate IAW the SOP... but whacked out power trip crap... no way. So if I want to eat in the bunk room I will... no company restriction and not a safety of flight issue regardless of what some power hungry captain might think.
