At 0.84, Goodwill Industries is the clear anchor of Thrift Stores' similarity graph — the gap between it and the next neighbor is nearly nine points, a structural spike that sets it apart from the rest of the top 10.
Beyond Goodwill, the neighbor set is almost entirely cross-kind. The second and third closest matches are Monro (0.75), an automotive maintenance chain, and McNeil (0.73), a miscellaneous entity — neither shares the thrift retail subcategory. What does recur is comedians: Daniel Tosh (0.73), Bert Kreischer (0.71), and Drew Carey (0.71) form the largest single subcategory cluster in the top 10 outside of Goodwill itself. The remaining neighbors span fast casual dining (Steak 'n Shake, 0.72), gas stations (Speedy Cafe, 0.72), department stores (Gabe's, 0.73), and casual dining (Red Lobster, 0.71) — a mix of value-oriented everyday retail and dining. Only Goodwill shares the Thrift Stores subcategory in the top 10.
The overall shape is one of a tightly defined core — a single near-twin in Goodwill — surrounded by an audience that also indexes toward comedians and budget-accessible food and service brands.
