When should a tanning facility refuse service to a client?

The correct choice reflects the importance of client safety and adherence to health regulations in the tanning industry. A tanning facility should refuse service to a client if they have contraindicated health conditions, such as certain skin conditions or medical issues that may be exacerbated by tanning, or if they are underage and do not have proper consent from a parent or guardian. This practice is crucial in preventing potential health risks associated with tanning, ensuring that services are provided in a responsible manner that prioritizes the well-being of clients.

In contrast, simply requesting a specific bed does not pose a health risk and falls within standard customer service practices. Similarly, being a first-time visitor is not a valid reason to deny service, as many facilities welcome new customers. Preferences regarding a tanning lotion also do not affect the safety or appropriateness of service. Thus, the focus on contraindications and age restrictions underscores the commitment to maintaining a safe environment for all clients.
