Purpose - Do customers recognize the effort and abilities of employees in service encounters? If so, to what extent do their perceptions influence customer satisfaction? The paper seeks to answer these questions. Design/methodology/approach - Two empirical studies, including a critical incident study and a video-based experiment. Theoretically, this paper builds on motivation theory, naive psychology, and attribution theory. Findings - Customers spontaneously and explicitly judge service encounters on the basis of service employees' effort and abilities, perceived through certain behavioral cues. The specific, direct impact of perceived effort and abilities on customer satisfaction varies for different service types. Research limitations/implications - Taking different dependent variables into account (e.g. customer emotions, customer loyalty and brand perceptions) might offer a valuable contribution to the fields of service or brand research. Practical implications - Companies must examine customers' perceptions of their employees' encounter behavior in depth to evaluate and effectively and efficiently manage perceived effort and abilities as the main determinants of customer satisfaction. They should acknowledge behavioral training represents a significant satisfaction management approach. Originality/value - The paper offers interdisciplinary theoretical foundation, brings in innovative research methods and combines content and methodology to a new scientific framework for the field of service research as well as practical application for companies.
