How often should water glasses be refilled?

Water glasses should be refilled by checking regularly and refilling when they are half empty or upon guest request. This approach reflects the high level of service expected in a fine dining environment, where attentiveness to the guest's needs is paramount. By monitoring the water levels in the glasses, servers can ensure that guests are consistently taken care of without requiring them to ask. This not only enhances the dining experience but also demonstrates a proactive and attentive service style.

Refilling upon request may lead to inconvenience for the guest, as they might have to interrupt their meal to ask for more water. Filling glasses every 30 minutes could either lead to waste if the guest doesn't consume much water or could disrupt the dining experience by being intrusive. Lastly, refilling only at the end of each course may leave guests feeling neglected in between courses. Thus, the best practice is to maintain a diligent and considerate approach by checking and refilling as needed.
