Do they operate the same format of car wash?

Format Autowash Headquarters Whistle Express Car Wash

Full Service 0.3% 3.4%
Hand Wash 1.5% 2.2%
Detail Shop 1.2% 0.6%

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.
