The term “independently owned and controlled” has reference to independence of ownership and control by others. Accordingly, the fact that the petroleum jobber may himself engage in other businesses which are not related to the enterprise engaged in the wholesale or bulk distribution of petroleum products, will not affect the question whether the petroleum enterprise is independently owned or controlled. For example, the fact that the wholesale or bulk petroleum distributor also owns or controls a wholly sep- arate tourist lodge enterprise or job printing business will not affect the status of his enterprise engaged in the wholesale or bulk distribution of petroleum products as an “independently controlled” enterprise.
