A little note on running the set. Set belongs to the boom operator. It's their domain. When I place a mic they notify operators, set dressing and/or props at the right times.
Boom operators of note keep the boom mic away from the mouths. They protect everyone, including me by being conscious of where the mic is pointed 100% of the time.
They know who to ask for what and where these people are all the time: operators, set dressers, on-set props, AD, the sound-friendly electric / grip.
What else?
