"I have seen zero Patron Education down here and it’s going to start right now"He has a point; there's not a performance that goes uninterrupted by chirps, blips and symphonic samples from someone's cel phone.
Back in the 80's, it was beepers; etiquette then was for patrons to leave the beeper in the box office; if it went off, an usher would come and gently tap you on the shoulder, and you'd leave the auditorium to respond to it. Of course, back then it was mostly doctors who used pagers, or other "on call" professionals. But that practice has fallen into disuse, and everyone and their child has a cel phone, and they can't seem to turn them off for even brief periods.
Best of luck, and welcome to the Blogosphere!
