As for the lunch - is the head director skipping lunch? Is there another time that you eat or could like the conference period butts up against lunch? I have seen an awful lot of directors do nothing during their conference period and then demand their duty free time. If you are hungry and need the time to eat then simply say you will get to it after lunch. Maybe you eat for 10 minutes, (I never spend more than that on lunch), and then you start prepping for the next rehearsal. Eat and then spend the last 10 minutes of lunch on a repair. I'd rather do that then spend an extra 2 or three hours after school trying to catch up what I could have done over the course of the day with better time management.
You might not have to blow everything sky high when it could be a really simple fix.
