The stage managers at Bristol rule all. They sign people in in the morning, sweep stages, deliver ice and water to stages, make sure shows start and end on time, keep the parade from wandering off into the Back 40, coordinate the Dead Parade, find benches, fix props, make sure fight cast's ropes are dry, and generally cover the butts of every performer on site.
They are among the first to arrive on site in the morning and among the last to leave. They're recognizable by their clipboards and walkies.
Just do what they tell you.
