In my area (mid-Atlantic), that already seems to be Tesla's modus operandi for Supercharger placement. In developed suburban areas, they're placed somewhere in a multi-use development / shopping center complex with at least a coffee shop, but more frequently a restaurant or two nearby. In rural areas they're typically co-located with a 24/7 gas station that has at least basic food service capabilities, or 'travel plaza' type development with a small assortment of convenience-type food vendors.
