This document summarizes key aspects of consumer behavior in the context of services marketing from Chapter 2 of the textbook "Services Marketing". It discusses the three stages of consumer decision making - the pre-purchase, service encounter, and post-encounter stages. In the pre-purchase stage, consumers seek to satisfy needs by evaluating service alternatives and making purchase decisions. Risk and uncertainty are higher for services due to their intangible nature. The service encounter stage describes customer interactions with service providers, which can range from high to low contact. Models for understanding these encounters include "moments of truth" and the "servuction system". Finally, the post-encounter stage involves customer evaluations after experiencing the service.
