Starbucks & Bookstores

Lately, I've been studying at a Starbucks connected to a Barnes and Noble.  It's pretty nice, stays open late, always had people studying, chatting, reading, and has a decent amount of electrical outlets.  The thing I've noticed the most since I've been hanging out here, the amount of people that come to Barnes and Noble and just read books or magazines but don't actually buy them.  It never fails, people are always hanging out there.  Did I miss the memo is Barnes and Noble the new hang out of singles and older aged individuals?  Should I start hanging out there; start "reading" books that make me seem deep and intellectual?
