Service quality is highly related to customer expectations and perception of service experiences (Fitzsimmons, 2011). Service quality can be judged by process and outcomes of services. Standard Operational Procedures implemented by McDonald is considered as the effective tool to provide the standard services based on hygiene practices. This allows McDonald to ensure high standard of food safety and services. Although McDonald seems to be successful in delivering high-speed services, this giant brand fails to maintain consistent service standard in each store. In many countries, McDonald is blamed for poor services such as unfriendly staffs, dirty and etc. Poor customer services are recognized as the urgent issue for McDonald. In the digital era, poor services offered by McDonald are widely known through negative WOM. In some store chains, clients are not satisfied with impolite and unfriendly staffs. Due to these facts, it is quite difficult for McDonald to enhance consistent service standard.
