A quote from he link to the video on Yahoo a few posts back. It is referring to the fact that the "altercation" was her getting kicked off because she was talking loudly and without regard to ANYONE on her cell phone. Sounds like after people tried to get her to tone down the annoyances she turned up the attitude.
"After the altercation, the conductor came on the loudspeaker and reminded people to keep conversations quiet, "especially those people who went to Harvard or Yale or are from Westport.""
