The presence of uniformed security guards acts as a deterrent to shoplifting activity. Guards are mostly used by high-end retail establishments such as jewellery stores and camera and electronics stores, but are also used by other retailers. Floor attendants greet customers, follow them as they walk about the store, and offer help with shopping. Shoplifters are not comfortable with this attention and may go somewhere else where they can steal unnoticed. In a 2008 global study conducted by NRMA, it found shoplifters are 68 percent less likely to commit the offense if they are greeted immediately as they walk into the retail store.
