What action should a server take to ensure a customer's safe journey home?

To ensure a customer's safe journey home, arranging for a ride service is the most responsible action a server can take. It prioritizes the customer's well-being by providing them with a safe mode of transportation once they leave the establishment. Calling a ride service means that the server is taking proactive steps to mitigate any risks associated with drinking and driving, as it helps prevent potential accidents and keeps both the customer and the general public safe.

In contrast, allowing a customer to drive themselves poses a significant danger, especially if they are intoxicated. Offering more alcohol can exacerbate the situation, leading to increased impairment and further endangering the customer's safety. Sending a customer walking home may also not be a safe option, particularly if there are concerns about the distance or their state of sobriety. Each of these alternatives fails to provide the necessary care and responsibility expected of a server in ensuring customer safety.
