    Hi Mike

    I think you want to know which employee rents the car. So to do this, add an entity employee in relation with
    Agency (0,n - 1,1) to propose the right employees list for each agency
    Rental (0,n - 1,1) if only one emplôtée manages a rental

    Just a comment, customer entity has to be in relation with Rental entity
