I was surprised that no one was able to break up the fight sooner.
I thought that it was common knowledge, that if you want to break up a fight between fashion models, simply wave some type of tasty greasy food in the air near the combatants. Something like a grilled cheese cheese sandwich works very well.
The scent will induce stomach spasms due to their bulimia and anorexia, and the fight will end instantly. It is very similar to the effect of headlights causing deer to freeze in the middle of a highway at night.
