Some people are talented at doing several things at once such as walking and chewing gum or talking and texting. One type of multitasking being seen more often in metro is walking and reading, not to be confused with standing and reading. Reading a book while standing on metro is easily accomplished (by most) by using the wall-leaning or one-hand-on-the-pole method. Walking through a station with your nose buried in a book is another story. You create a slow-moving, unaware, and often clumsy bump in the flow of people through a station. Not only could you potentially run into someone else, but those pesky posts and faregates in the station could interrupt your reading. Don't get me wrong, I understand the pain of putting down a book at its climax can be tough but reading a book is best saved for moments when you are stationary.
All the above also goes for newspaper readers, because while obnoxiously opening your full-sized paper and wrapping it around your face while walking through the station may entertain onlookers, it really does cause the same problems as the book reader-walkers.
