Final answer:
Customers can be difficult when selling intangible services due to negative experiences with publicity and sales tactics, which leads to skepticism and lack of trust.
Step-by-step explanation:
When selling more intangible services, customers can be difficult due to their past experiences with negative publicity or dishonest sales tactics. These negative experiences can lead to a lack of trust, making customers skeptical and hesitant to engage with the seller. This makes it challenging for sellers to build a positive relationship with potential customers and convince them of the value and credibility of their intangible services.
