Service quality perception wildly has been studied in last three decades. Zeithaml (1988) define service quality as an assessment of customer from the overall excellence of service. It is because of service quality nature, which is intangible, heterogeneous and inseparable. In recent decades, many models have been developed for measuring service quality and the first attempt was by Gronroos in 1984. He believes in distinguish between technical quality as an outcome for performance of service and functional quality as a subjective perception of service delivered. Rust and Oliver have expanded Gronroos model in 1994 by adding service environment as a new dimension.
