Unfortunately you don't actually need to read the books in order to sell them. Infact I don't ever recall a bookstore employee talking to me about any book, ever! I go into the store, walk around, find a place I like, look at the descriptions, and never, ever... has an employee walked up an begun a conversation. They only talk to those people who address them, and ignore everybody else. I had one I liked once and she was making coffee, she was so sexy... grrr Anyway she was nice so I asked her out, she said "I have a boyfriend" even though she already finished telling me how she'd just moved there an was new to the area, lying beotch!
So yeah, bookstores don't take much to work for, the people that think that are nutso. I read alot + listened to alot of sci-fi books but nobody cares if you do that, they all want to hear "I've read all the same books as you".
Oh well :-Z
