The trick is to walk around with a paper an clipboard, no one ever bothers the guy walking around writing things down on a thick stack of paper on a clip board.

Plus if you do get caught you get a total sense of satisfaction showing off how you fooled everyone into VIP access by drawing doodles of naked women.
