Yup, Cochran is VERY well-known to house staff around the city- her old baseball cap, her huge Duane Reade bag full of random items. My front of house friends all shared this on Facebook, with varying degrees of disgust. One of my first jobs in the city was ushering at the Public, and she is infamous there for the issues she causes- everything from taking seats that aren't hers to getting into fights with house management. She is rude, disruptive, and frequently hostile to audience members and house staff that prevent her from getting what she wants.
As Vespertine says, she's been banned from buying tickets from the usual discount channels and has been banned from quite a few theatres, too. She trolls Showcase code productions in NYC, which allow Equity members free tickets if any are available before the performance (and she is an Equity member- don't worry, she has been to known to make problems there, too), and creates a fuss if nothing is available.
She may be a pitiable-looking senior citizen, but no one who works in New York theatre who has had to deal with her will have any kind words on her behalf.
"...everyone finally shut up, and the audience could enjoy the beginning of the Anatevka Pogram in peace."
