Able Builders, Inc., contracts with Beach Investment Company to build a Cool Juice 'n Fruit stand near Delta Beach. The work is to begin on April 1 and be done by June 1, so that the stand can open for the summer. Able does not finish until June 14. The stand opens but Beach Investment loses two weeks' early summer sales due to the delay. Is Beach Investment's duty to pay for the construction of the stand discharged?
