Allison Holmes has just been promoted to the job of Regional Beverage Manager at Appleboy’s Restaurants. Her district includes six successful units. In one unit, Allison suspects that Ron, the restaurant manager and Tony, the bar manager, have collaborated to defraud their restaurant by serving cash paying guests at the bar, not ringing up the sales, and then splitting the revenue collected from those guests. Since the unit’s cash drawers are always in balance, no one has previously investigated the possibility of employee theft in this unit. What are some indications of such fraudulent activity that would lend support to Allison’s suspicions? How would you suggest Allison find out if she is actually correct?
