In the functional market economy, due to the intense competition, the service suppliers are forced to consider, as far as utility and the tariff of the services are concerned, the needs, requests and expectations of the consumers. This fact is imposed with necessity because the consumers are better and better informed and trained, becoming more demanding, and as such more and more often they preffer purchasing services of the best possible quality at the lowest tariff. Therefore the managers and employees of the firms in the hospitality industry (the tourism agents, hotels, restaurants etc) should have the interest of offering only good quality services on the market at the lowest possible tariffs, so that they could keep their clients and even win more clients, in order to continuously increase the business figures, the profit and the market segments.
