The Buyer for the Motel Chain Told the Interface Carpet

Short Answer

The buyer for the motel chain told the Interface carpet salesperson who was selling carpet made of corn instead of petroleum-based nylon, said, "I just have to believe that if I need replacement carpet tile down the road that Interface will not have them because this is some kind of environmental fad." The Interface carpet salesperson responded, "I can assure you the product is not a fad. Interface would not have invested millions of dollars in perfecting this technology if it were a fad." Why is the use of direct denial imprudent in this situation?
