I wish there was an industry standard number of stupid questions and/or ridiculous emails I could receive from a single actor before I could rescind their audition privileges. "Sorry, Timmy. That's the third time you asked about the audition start time, despite it never changing. I answered the first two instances, but now I'm invoking the 'Stage Manager Ain't Got Time for That' rule, and your slot will now go to someone with reading comprehension skills. You are on six months probation, and we *do* keep a list."
Of all the people who's life you should want to make easier, actors, it should be the stage manager.
