Describe how the ''Store'' came to existence

Grandmother had owned the "Store" for twenty-five years. The store got its start at the beginning of the century, when Grandmother would sell lunches to the men working in the area. Laborers from the lumber yard and the cotton gin would prchase their lunches from her mobile counter. Afew year later, Grandmother built the store in the heart of the town's "Negro area", and it had been there ever since.
