When I was shooting sunset photo handheld ( <a href=" http://www.zeissimages.com/showphoto.php?photoid=31568&showall=1 " target="_blank"> http://www.zeissimages.com/showphoto.php?photoid=31568&showall=1 </a> ), this Pro come out of nowhere and interfere between my object and my lens. He haven't taken a single shot before I left but instead he force me to narrow my angle of view.
