CLARKSVILLE, Tenn. — On a hot July morning, customers at the Dollar General along a two-lane highway northwest of Nashville didn't seem to notice signs of the chain store's foray into mobile health care.
A woman lifted a child from the back of an SUV and walked into the store. A dog barked from a black pickup truck before its owner returned with cases of soda. Another woman checked her hair in a convertible's rearview mirror before shopping.
