Here's why:
* Direct Customer Interaction: Nail technicians provide a direct service to their clients, offering personalized treatments and care.
* Skill-Based Service: They use their skills and knowledge to enhance the appearance of their clients' nails.
* Intangible Product: The result of a nail technician's work is an intangible product - improved nail appearance. It's not a physical good that can be bought and sold.
While there is a small element of "production" involved in the sense that they are "producing" a finished look, the primary focus is on providing a service to the customer.
