Dopson's Hardware was in bad financial shape. It owed so much money that vendors put the store on a cash-only delivery basis. As a result, the store had a dwindling inventory of goods to sell. Whenever a customer asked about an unavailable item, the owner directed the sales staff to say that it was on backorder and would be in stock next week. When the customer returned, the item was still unavailable. The owner's policy created a(n) __________ gap.
