sweethearting
n.— «One of the primary methods used by employees is “sweethearting,” theft carried out by collusion between an employee and a customer. It is so named because it most often occurs between a cashier and his family members or friends. With sweethearting, a cashier may fail to charge the customer for some items or may ring up only one item of a multiple purchase.» —“Minding the Store” by Jeff Morris Multichannel Merchant June 1, 2005.
