Who manages the audience

Hi,
So there are many wonderful stories about actors stopping a play when people are using their cell phones or behaving otherwise indecorously. (another discussed below) Whose job is it to manage the audience? What does an artist do if the management is poor or ineffectual? OR what about the traditions of chinese theatre or for that matter Renaissance and Restoration -- even up through the early 20th century theatre was highly interactive. How does an audience know how to behave?
