When is it appropriate to offer drink refills to customers?

Offering drink refills when customers' glasses are low and upon request is appropriate because it demonstrates attentiveness and responsiveness to the customers' needs. This approach enhances the dining experience by ensuring that guests have enough to drink without being intrusive.

By observing the level of the customers' drinks, servers can proactively provide refills at the right moments, which can improve customer satisfaction. Additionally, offering refills upon request allows customers to have control over their dining experience; they can choose when they would like more to drink.

In contrast, only offering refills when customers specifically request them can lead to a less attentive service experience, as it may leave guests waiting longer if they don't vocalize their need. Indicating that a customer is finished is not a suitable time to offer refills, as it implies they are no longer interested in additional beverages. Serving drinks after every meal might be excessive, especially if customers are still working on their drinks, leading to waste or unwanted interruptions.
