Final answer:
Services where the customer visits the site include hairdressing salons and pet grooming facilities, which are examples of economic activities depending on customer presence.
Step-by-step explanation:
Examples of services where the customer visits the site include a hairdressing salon and a pet grooming facility. These are economic activities where the customer must be physically present for the service to be performed. In contrast, mobile car washes come to the customer, plumbing services and home cleaning are provided at the customer's location, and catering services are delivered to events.
Services are considered economic products because individuals are willing to pay for the execution of these tasks by others. A key distinction to remember is between goods and services, with the former being tangible items that one can hold, while services, such as haircuts, insurance, or dental visits, are intangible but hold value to the recipient.
