Drive-thru operations at Dunkin'® locations create a specific theft environment: high transaction velocity, multiple cashier rotations, and physical separation between the order taker, the product assembler, and the payment cashier. This separation creates gaps where product giveaways — free drinks given to friends or family members — are difficult to detect in real time and almost impossible to identify after the fact without video correlation.
At a busy Dunkin'® drive-thru processing 300+ transactions between 6–10 AM, a cashier giving away 10 beverages represents $40–$60 in daily product theft. Five days per week, that's $200–$300/week, or $10,000–$15,000/year from a single employee. The math is devastating at scale — and most operators don't discover it until the pattern has been running for months.
Beyond sweethearting, Dunkin'® drive-thru cash handling creates register manipulation opportunities. Voids processed after a customer pays cash, no-sale drawer opens during rush periods, and discount application patterns that don't match legitimate promotions all surface in DohShield's daily POS exception analysis — correlated with video of the transaction to confirm the behavior.
