The queue at popular bookstore is insanely long cum slow. And I realized how inconvenient it is to go from hall 1 to south spine, haf to walk thru hall 5, hall 4 then reach s3. Juz to buy 2 tbs, I walked 10-15mins to popular, queued 30 mins, then walked 10-15mins back to hall 1. What a waste of time!
