Subway® Loss Prevention: Protein Theft, Discount Abuse & Register Fraud

Protein Over-Serving Detection

Camera monitoring of the sandwich assembly area documents portion sizes for protein additions. Over-serving patterns — employees consistently adding extra meat beyond spec — are identified by employee, shift, and time period. When protein over-serving is confirmed by video, operators have documented evidence for corrective training or discipline, rather than a food cost discrepancy with no explanation.

Cash Manipulation During Manual Entry

Subway®'s manual order entry process creates POS manipulation opportunities. DohShield analyzes all POS exceptions — voids, refunds, no-sales, discounts — and correlates them with video of the transaction. Void patterns that cluster around cash transactions, timing anomalies that suggest voiding after payment received, and unusual no-sale frequencies during specific shifts all surface in daily exception analysis.

Unauthorized Discounts and Coupon Abuse

Subway® offers various promotions and discounts, but unauthorized discount application — employees discounting transactions for friends or family, or applying expired promotions — is detectable through POS analysis. DohShield identifies discount rates by employee and shift, flagging outliers that don't match the expected distribution of legitimate promotional usage.

After-Hours Access Monitoring

Unauthorized access to the store after hours — employees who have keys or access codes returning after closing — is a significant loss vector at small-format Subway® locations. DohShield monitors after-hours door and camera events to identify unauthorized access patterns.

Employee Meal Abuse

Employee meal policies at Subway® are specific about portion and timing. Employees using their meal benefit outside policy, making additional unauthorized meals, or sharing their benefit with non-employees represent measurable food cost losses that accumulate daily across a multi-unit portfolio.
