RuthlessChicken - you are correct. In the Atlanta Encores programs they have a page on theatre etiquette in the back. I actually posted it in a thread over 2 years ago. Here it is:
Golden Rules:
Here's a refresher course. Please read on, and remember, part of one's pact as an audience member is to take seriously the pleasure of others, a responsibility fulfilled by quietly attentive (or silently inattentive) and self-contained behavior. After all, you can be as demonstrative as you want during curtain calls.
1. Go easy with the atomizer; many people are highly allergic to perfume and cologne.
2. If you bring a child, make sure etiquette is part of the experience. Children love learning new things.
3. Unwrap all candies and cough drops before the curtain goes up or the concert begins.
4. Make sure cell phones, beepers, and watch alarms are OFF. And don't jangle the bangles.
5. The overture is part of the performance. Please cease talking at this point.
6. Note to lovebirds: When you lean your heads together, you block the view of the person behind you. Leaning forward also blocks the view.
7. THOU SHALT NOT TALK, or hum, or sing along, or beat time with a body part.
8. Force yourself to wait for a pause or intermission before rifling through a purse, backpack, or shopping bag.
9. Yes, the parking lot gets busy and public transportation is tricky, but leaving while the show is in progress is discourteous.
10. Honor the old standby: Do unto others, as you would have them do unto you.
My personal favorite is the one about lovebirds.
"This table, he is over one hundred years old. If I could, I would take an old gramophone needle and run it along the surface of the wood. To hear the music of the voices. All that was said." - Doug Wright, I Am My Own Wife
