To deter these thefts, retailers use various security measures, such as security cameras, alarm systems, anti-theft tags, undercover store detectives, and exit alarms. Shoplifting poses a significant challenge for retailers. While not every customer exhibiting unusual behavior is a thief, understanding the subtle cues associated with shoplifting can be a valuable tool in loss prevention. Observing these behaviors allows staff to increase vigilance and potentially deter theft before it occurs. It's crucial to remember that these signs are not definitive proof of guilt, but rather indicators that warrant closer attention.
