What is Rogers' Auto Service and Supply

In "A Sense of Story," Rogers' is the Detroit auto repair shop where conflict over one mechanic's invention of a lubricant to extend the life of foreign cars apparently leads to his murdering his boss. The shop is one of three owned by a white man, Orion W. Rogers, who integrates his work force years earlier at the white manager's - the deceased - recommendation. There are no traces of racial strife in the shop, although socializing does not extend to visiting one another's homes.
