This document discusses consumer behavior in service encounters. It defines the consumer decision process as having three stages: pre-purchase, the encounter, and post-purchase. In the pre-purchase stage, consumers go through problem recognition, information search, and evaluation of alternatives. The encounter stage involves purchasing/consuming the service and any emotions involved. In the post-purchase stage, consumers assess the value of consuming the service. The document also discusses factors that influence customer expectations, such as internal factors and competition, and strategies to enhance customer perceptions like accurate satisfaction measurement and managing each encounter.
