     * It looks like we should be able to use ->first() here and
     * return an object instead of a collection, but we actually
     * cannot.
     *
     * In short, you cannot execute the query defined when you're eager loading.
     * and in order to avoid 1001 query problems when displaying the most
     * recent checkout note, we have to eager load this.
     *
     * This means we technically return a collection of one here, and then
     * in the controller, we convert that collection to an array, so we can
     * use it in the transformer to display only the notes of the LAST
     * checkout.

     * It's super-mega-assy, but it's the best I could do for now.
