I've had mostly good experiences with this particular location, but my one qualm comes with the way that the staff and especially the security guard seem to keep an eye on the customers in a way that makes me a tad uncomfortable.  As I'm browsing the books on any given shelf, I will often catch the security guard looking directly at me from across the store, as if I'm doing something suspicious.  I also feel like the staff sometimes get nervous when customers are spending too much time walking around the store and not sitting in either the cafeteria or the chairs.  Maybe this is the way that people who steal from bookstores act.  I don't know.  All I know is that I'm not a thief and unless the alarm goes off when I exit the store there's no reason to suspect me of anything.
