Concept:Small scale retail outlets succeed by building close, personal relationships with their customers.
Explanation:Small retailers operate in local areas and serve fewer customers than large stores.
This allows them to interact directly with each customer and understand their specific needs.
They can offer individual attention, advice, and a friendly shopping experience.
