The guy that leaves his presentation in the cab:  Why doesn’t he just call the cab company and have them send the cab back to where he is standing…..  it won’t be more than a couple blocks away.  Knowing how long it can take to actually print out a thick book sized pile of pages….  it would be quicker to get the cab to bring it back.  Not to mention the tree-hugger aspect of reprinting a book that size.
