 FAIR: In the opening scene, Sulus tea cup faces its printed side  toward the camera which looks at Sulu, then Sulu drinks from it, we  do not see him place it down. We see the cup next from Sulus  perspective, which is clear because not only is the printed text  missing, but the handle is now on the other side. Other than the  text and the handle, there is no other reference in either frame to  determine which way the cup is facing, so there is no goof.
