Adam and John are housemates. Adam is a fish seller who sells salmon imported from Norway in the local market. On the eve of a public holiday, Adam was supposed to join his family on a ship cruise. However, he received large quantities of frozen salmon from Norway. He stored the fish in the freezer at their house during the holidays, and joined his family for a 3-day ship cruise. While he was away, a great storm caused their main electricity cable to burn and their house had no electricity. The salmon thawed out. John who was staying home for the holidays, tried to contact Adam but could not get him. John therefore decided to sell the fish as fast as possible and took the fish to the market. Three days later when Adam returned from his trip, he was very shocked to find all the fish had been sold at half the market price. Advise Adam.
