One inventive and sly employee assisted retail store crime I have seen a report on is the WalMart "cash back" scheme. I am sure it likely has caught on at many other stores by a host of teen age n younger adult employees who can not help themselves. They can not help it but must constantly brag to everyone via the latest curse of humanity, known simply as (social media) in this day and age.
So the "cash back" scheme is about as simple as they come.
Employee at register flags one of her accomplices who are always close and on standby to jump into the check out line behind this person with huge order , plenty unruly kids she is watching or who looks like they have lots of money. Checker instantly goes from angry , dont want to be here employee face/attitude to the "hi and welcome to our store , isnt it a wonderful day? Did you find all the products you needed?"..... employee who is trying to now confuse or catch off guard the customer as she is checking out her purchases in hopes this customer is going to be too distracted to look too close at her store reciept. Why? Because the store checker has typed in the "cash back" option to the tune of anywhere from $20 to $100. This way when customer leaves , accomplice simply moves up next to check out a news paper, a bag of M&Ms, soda or bubble gum etc.... and to recieve her reciept with the cash concealed, under handed (attempts to hide from camera) the "cash back" charged to previous customer's credit or debit card.
