Imagine you are a consultant working with a luxury spa that offers various services, including massages, facials, and wellness treatments. The spa has been receiving feedback about customers' perceptions of waiting times and its impact on overall satisfaction. Customers sometimes feel the waiting times are longer than they actually are, affecting their overall experience. The management is keen to address this issue to enhance customer satisfaction and loyalty. Which psychological factor could significantly impact customers' perception of waiting times? 1. Customers tend to overestimate wait times when the spa services involve multiple steps or intricate procedures. 2. Customers feel that their wait time is shorter when provided with engaging content, such as soothing music, aromatherapy, or a tranquil waiting area. 3. Customers perceive shorter wait times when they are waiting alone rather than in a group or with others, especially during peak hours. 4. Customers feel more satisfied with shorter wait times if the spa introduces a dynamic scheduling system, providing unexpected availability for popular services
