Lois was someone people actually wanted to talk to, and she would share her tips with other top fans or people who asked (I believe for the most part), about among other things, upcoming performance schedules and what operas singers were doing, last minute cancellations, etc. that she got many times from the singers or their managers themselves. Unlike stories about that other lady, I don't think Lois ever made a nuisance of herself about finding tickets -- she usually sat way up high anyway, and she was legally blind with thick glasses and binoculars. She was so much of a fixture that she was almost like a minor celebrity to opera cognoscenti in the lobby and auditorium. I think there was more controversy with the other lady you mentioned, including her methods of getting tickets; there are testimonies of some actively avoiding or having words with that lady being in their seat, etc. Lois wasn't controversial; she just was rather admired as a superfan who was ultra-knowledgeable and passionate about opera.
