2. A local entrepreneur who has been running a profitable business for many years recently purchased a three-way liquor license. This license gives the owner the legal right to sell beer, wine, and spirits in her restaurant. The cost of obtaining the three-way license was about $75,000, since only 300 such licenses are issued by the state. While the license is transferable, only $65,000 is refundable if the owner chooses not to use the license. After selling alcoholic beverages for about a year, the restaurateur came to the realization that she was losing dinner customers and that her profitable restaurant was turning into a noisy, unprofitable bar. Subsequently, she spent about $6,000 placing advertisements in various newspapers and restaurants magazines across the state offering to sell the license for $70, 000. After a long wait, she finally received one offer to purchase her license for $66,000. What is your opinion of the restaurateur's decision? Would you recommend that she accept the $66,000 offer?
