My oh my, what tangents I follow:
Piggly_Wiggly, the inventor of the self-service grocery store.
Piggly Wiggly was the first to:
- provide checkout stands.
- price mark every item in the store.
- feature a full line of nationally advertised brands.
- use refrigerated cases to keep produce fresher longer.
- put employees in uniforms for cleaner, more sanitary food handling.
- design and use patented fixtures and equipment throughout the store.
- franchise independent grocers to operate under the self-service method of food merchandising.
