Do they operate the same format of car wash?
| Format | Trademark Car Wash | Tsunami Express Car Wash |
|---|---|---|
| Express Tunnel | 1.5% | 6.4% |
| Detail Shop | 1.3% | 2.4% |
| Hand Wash | 2.5% | 1.1% |

Format share is computed across customer review mentions, not over locations. A chain with mostly express-tunnel sites but heavy detail-shop talk in reviews will show both at non-trivial rates.
