I use the public library for books, for book shopping (do I want to buy this? I'll check it out first), and if my internet access is down, for the internet-connected PCs. When I was writing my thesis I used the bigger library in the county town for reading dissertations on microfilm a lot, and for interlibrary loans. The librarians there...didn't like me, and the library had a lot of drawbacks. They had a quiet reading room, but it was next to a place where they taught job-seekers computer skills, and there were always people standing around the door making phone calls.
They used to have the microfilm machine up on the 4th floor with local history, and I don't think anybody used that room but me, but then they moved the microfilm machine to right next to the checkout desk, in fact next to the opening the librarians had to go through to get to and from the area behind the desk, and they didn't like me being there. One of them used to, no joke, kick me or my chair every time he went past, and then make a joke of it.
Another time the head librarian went into a loud rant to the others about this "one reader" who was costing them so much money, why, it cost them £70 to borrow this one dissertation and "the reader" only had to pay £3.50! I just ignored her, but could have said "then raise your prices; it's not my fault that I only paid you what you asked me to pay you!")
Last one (I promise) -- when I was double-checking references just before I turned the thesis in, I needed to take out 13 books, but we're only allowed 12. I showed the librarian that four of the books were really the four individual volumes in a set, and asked to be able to take 13, just for a short time, just to check references. No, that wasn't permitted. So I said I'd bring them back in a week, instead of a month. She said "You can't read 13 books in a week". (A small part of me wanted to say "Maybe *you* can't...") I explained again about the reference checking, that I wasn't planning to read them all in a week. She put her foot down: absolutely no more than 12 books.
But 5 of the books (I'd reserved them on-line) were waiting for me at a branch library, so I got the 7 books there, and I went out to this branch for the others. I stood at the counter, dithering, and the librarian there asked me what was wrong. I said I couldn't have them all, because that would be 13 books, so I was trying to decide which 4 to take, because I was checking references, and she said "Take them all! What kind of service would we be if we didn't let somebody have an extra book now and again?" I could have kissed her!!
And then a few years later we moved, and now the *nice* librarian's branch library is the nearest library, and the one I use all the time. Good result!!
