Professor Farnsworth criticizes this common definition of waiver as imprecise and offers the following alternative definition:  ". . . the excuse of the nonoccurrence of or a delay in the occurrence of a condition of a duty."  Farnsworth, Contracts 540-41 (3d Ed. 1999).  How would you apply his definition to this case? 

     Suppose that after receiving payments for a few months, Holiday Hospitality Franchising told the plaintiffs that they no longer had to pay any franchise fees.  Would that constitute a waiver?  See R.2d Contracts 84(1).
