Johnny decided to order organic fruit for his restaurant from a new supplier, George. When he reads through the terms of the written contract given to him by George, he sees that while George guarantees that the fruit will be 'fresh', the contract says nothing about whether the fruit will be organic. Johnny asks George about this, explaining that he tells his customers that his fruit is always organic. George assures him that the fruit will always be organically grown. Johnny then signs the contract without changing it. The next three deliveries include fruit that is not organically grown. Can Johnny legally enforce George's verbal promise about the fruit?
