hospitality is an important sector in services particularly in the developed countries. Under the services sector, the hospitality is often named as the number one industry worldwide in terms of generation of income and employment. Over the last three decades, the hospitality has grown rapidly, and now it has become one of the most prominent sectors of the service industry. It produces over 11 percent of the world’s gross domestic product and employs over 10 percent of the global workforce (UNWTO, 2003).
