Did she look as much like a weird, elfin little space alien in person as she does in pictures? I actually like Laurie Anderson a LOT, but she's an odd woman.
I sold coffee and housewares to many celebrities when I was in grad school (Elvis Costello, Matthew Broderick, Melanie Griffith, Holly Hunter, Francis Ford Coppola, among others), but the only one who was an a--hole was Chris Kattan from Saturday Night Live. Of course, he hasn't worked in awhile, so maybe he will be serving coffee to me in the near future.
I ran across another FReeper on a thread who was was IN Laurie Anderson's band.
