cheaper than hourly rate hotel
Right, I don't own the chair, cos my name isn't on it. But what about me settling down at the chair, placing my bag beside it, then went to the shelves to look for books, and returned to find a guy sleeping on the same chair? Yeah, he pulled the chair slightly away from the original spot, so it looked like my bag wasn't beside it anymore.
He's far from being the only guy sleeping in the library. While moving from shelf to shelf to look for books, I found many similar sights at level 4 of NUS Central Library. Most of these guys don't have books or stationery with them, it looked as if their only purpose in the library was to sleep! I do agree that maybe we get tired after reading for a while, but at least if you hug a book or something, it looks more convincing.
Sure beat opening a room at an hourly rate hotel at Pasir Panjang Road. (and I have heard "hot" stories happening inside the library)
