I don't recall there being any in Act 1...then again I couldn't get out of that hellish experience fast enough so I might not have noticed.
But I do know there was a sign or announcement saying there would be in the play. (And more if people didn't turn off their cell phones, etc.)
Experience live theater. Experience paintings. Experience books. Live, look and listen like artists! ~ imaginethis
LIVE THAT LESSON!!!!!!
