Many studies show that satisfaction with a service provided is based primarily on the quality of service provision (Hunt and Ivergard, 2015, 47). A quality of service depends on many factors, among which one of the most important is education of the staff that provides services. This study analysed only one dimension of that education, e.g., relationship to the physical appearance of a client and the possible impact on the quality of the service provided. This is why we used a group of social workers who, during the course of their studies, are taught about how their clients’ physical appearance can impact their relationship with their clients and, consequently, the assessment of the quality of services provided by the clients.
