Peter Marks: “It is every patron’s right, I suppose, to consume theater in any way they see fit, as long as it is not a nuisance to others. The steady mechanical breath of sleep can be an audible distraction at a quiet play, and yes, a throat clearing or a whispered word of correction is required if snoring commences. But the greater injustice, it seems to me, is the one unconscious theatergoers do to themselves. Buying a $100 seat is an inordinately expensive way to take a nap. Is every theater piece really that dull to some percentage of the crowd, I wonder, or are we just coming to public events ever more sleep-deprived? “
