Harlan F. Stone,
United Fuel Gas Company v. Railroad Commission of Kentucky…
“ The primary duty of a public utility is to serve on reasonable terms all those who desire the service it renders. This duty does not permit it to pick and choose and to serve only those portions of the territory which it finds most profitable, leaving the remainder to get along without the service which it alone is in a position to give. An important purpose of state supervision is to prevent such discriminations, see New York & Queens Gas Co. ”
