In the real world, Leslie Browne's character would have gotten a major repremanding after her drunk episode. No ballet company, ESPECIALLY the premier ballet company in America, would tolerate those kind of antics for one bit. They are extremely strict.
If you are a corps member, and your leg is not matching the height of the person's leg in front of you, you get yelled at. So imagine the trouble you get in when you're drunk and messing up the entire scene!
This scene pissed me off.
