The document discusses consumer behavior in services across three stages: pre-purchase, service encounter, and post-encounter. In the pre-purchase stage, consumers go through need recognition, information search, and evaluation of alternatives. During the service encounter stage, consumers interact directly with the service provider. In the post-encounter stage, consumers evaluate the service experience and determine their satisfaction level based on whether expectations were met or exceeded. Understanding these three stages of consumer behavior is important for service organizations to create satisfying customer experiences.
