Fayetteville Police Department spokesman Dan Grubb said the money was concealed in the box Friday morning by a store employee who intended to have another worker hand it off to her through the drive-through so she could make a deposit on behalf of the shop, the Fayetteville Observer reported Tuesday.
"She (the employee) places the box near the windows and goes to her car," Grubb said.
However, a worker at the window who was unaware of the plan gave the box to a customer who placed an order.
"The customer left with doughnuts and a $5,000 bonus," Grubb said.
The spokesman said the customer has not been spotted at the store since the Friday morning incident.
