I recently got the job of a security guard at a local retail store. What is the appropriate way for a retail store security guard to deal with a shop lifting incident?
Answer: First, wait till the customer tries to exit the store; once they are out, immediately raise the alarm, though in most stores these days, it will be automatic when the tag isn’t removed at the checkout. Then follow the customer out, and quietly approach them and appraise them that their shop lifting has been caught on camera. Nine out of ten shoplifters do it for the thrill, and will quietly pay for the merchandise. Very few people will try to run with the items and risk the police being called.
