Which of the following best defines the function of FR3?

The function of FR3 is best defined by the answer that involves running to provide alternative products for customers. This role emphasizes the active engagement of staff in ensuring customer satisfaction by promptly addressing their needs, particularly if items are unavailable or if customers are seeking additional options to try on. This proactive approach enhances the shopping experience and aids in facilitating a more comprehensive selection for customers, which can ultimately lead to increased sales and better customer service.

The other options, while related to customer interaction and the fitting room environment, do not capture the core focus of FR3. Greeting customers contributes to a welcoming atmosphere, performing alterations adds a service dimension, and maintaining cleanliness is important for the overall aesthetics and hygiene of the fitting room. However, providing alternative products directly reflects the dynamic assistance that staff can provide, reinforcing the importance of adaptability in customer service roles.
