There's nothing wrong with talking to women in a bookstore, but it's easy to fuck up. If you just interrupt a woman and start hitting on her than sure, that's special fellow shit. BUT if you're both in the African American literature section, overhear her ask a clerk if they have Invisible Man ("sorry, we don't but you can order it at our online store"), then you casually say "they should just rename this section 'black romance paperbacks' to get rid of the confusion...." well my man, you just might find yourself getting her number.
