Subway's top 10 nearest neighbors span six different categories — QSR, Fast Casual Dining, Footwear, Miscellaneous Services, Automotive Parts, and Eyewear — with no single entity pulling far ahead of the rest.

The shape is flat: scores run from Pizza Hut at 0.84 down to Walmart Pharmacy at 0.81, a spread of just 0.03 across all ten positions. McDonald's is the only other QSR in the top 10 (0.83), and Pizza Hut is the only Fast Casual Dining entry — meaning the restaurant category accounts for just two of the ten slots. The remaining eight neighbors are drawn from entirely different sectors: Shoe Dept Encore (0.83, Footwear), two Services/Miscellaneous entries at 0.82, O'Reilly Auto Parts (0.82, Automotive Parts), Walmart Vision Center (0.82, Eyewear), Parts & Accessories (0.82, Automotive Parts), Dollar General (0.82, Discount Stores), and Walmart Pharmacy (0.81, Pharmacies and Drugstores). The dominant thread running through these non-restaurant neighbors is value-oriented, everyday-errand retail — auto parts, discount stores, pharmacy counters, and footwear chains that serve similar shopping occasions.

The flat, cross-category spread suggests Subway's audience is defined less by food preferences than by a broader pattern of practical, accessible consumption that it shares with a wide range of everyday retail and service brands.
