Chapter 18 identifies four levels of service in retailing--self-service, self-selection, limited service, and full-service. Visit at least one of each type of the described retailers and are to comment vis--vis the retailer-positioning map (Figure 16.1). Answer the following relative to your shopping trip: Did you experience a dissonance between the service you received and their initial characterization of the store? In other words, did you receive "better" service than you initially expected to receive from a self or limited service retailer? Did you experience a "lack" of service from the store you perceived as "full service"? If either of these conditions occurred, postulate a causal relationship for the occurrence.
