Final answer:
Whether explicit music can be played in a restaurant doesn't depend solely on the age of the individuals present but also on local laws and the restaurant's own policy.
Step-by-step explanation:
Whether a team member can play explicit music in a restaurant, even if everyone present is over 18, depends on the laws of the jurisdiction and the policies of the restaurant.
While age may make it permissible for individuals to hear such music, businesses must adhere to local laws and regulations which may include limitations on explicit content due to various reasons such as maintaining a certain atmosphere, or complying with public performance laws. It is also essential for the establishment to consider the restaurant's policy itself, as the management may have specific rules against playing explicit music to preserve a particular environment or out of respect for customer preferences.
