As an old hand at the video game
, let me tell you, it's 50% about the customers, 25% keeping the returns and retail on the shelves, and 15%-20% making the place look shiny, and 5%-10% watching out for thieves. People slitting DVD with razorblades was a big problem, and someone even figured out how to use a fridge-magnet to open the mag-locks on the hard plastic around the retail product. Only other advice I can give is to know your product (aka, watch as many movies as you can get away with, especially the big-name new releases... even if you're 'iffy' on them), and to watch out for SCs. Hope you end up working with a crew as great as the one I was part of during my stint.
