I'm going to embarrass my cred by getting some details wrong, but an acquaintance worked at one of the longest-lasting music sheet stores in Manhattan, across from Lincoln Center, I believe across from Lincoln Center. A place that had every score you could need.
Buckley wandered in one day, not to find music. She didn't even know what the place was for, just walked in. Then hung out there all day long, just having a good time, I guess talking to the staff or whatever, the details were vague. She never bought anything. The acquaintance was very amused, and there's no dirt. Nothing bad happened. It was just odd someone so long a part of musical theater at that point in her career would walk in completely unaware of what they sold or their reputation and then, no desire to purchase anything, just hang out all day or at least for several hours. He had good memories of it, and the way he spoke of her was amused and a little baffled, not offended or put off.
