With the changing of the times, the modern museum has taken on more and more varied functions. It has not only become a collection, research, exhibition and education space, but also a place for sightseeing, recreation, entertainment and self-learning. A closer relationship is developing between the modern museum and the public and the modern museum is becoming increasingly important in people’s lives. When the value of museums is recognized, changes must come about in the operating attitude of museums. They must provide enthusiastic service to the public and be ready to accept criticism and complaints. Museum visitor complaints are mostly concerned with exhibitions, activities and facilities. Complaints represent a feeling of disappointment from the expected experience. Providing visitors an appropriate channel for submitting complaints can alert museum staff to inappropriate exhibitions, events, activities and behaviors and give them the opportunity to take corrective action. How should museum staff deal with various complaints? The answer is sincerely and promptly. Museum staff should intently listen to visitor problems and look at issues from the visitor’s viewpoint. Museums eager to improve service need to start by changing their attitudes. Vigorous response to and effective handling of complaints are essential. Visitor complaints must be viewed as valuable feedback and one of the most available sources of information.
