You can put 50 etiquette sheets in a Playbill and still people will ignore them and do what they want. Once they start getting ejected from a theater and lose their money they will think twice the next time. Of course there are some who will continue to do what they want no matter how much it costs them.
Imagine someone waits 6 months and pays a gazillion dollars for a ticket to The Show and than gets ejected for bad behavior. This would bring a smile to many faces.
