Which action aids in showing attentiveness while delivering drinks?

Showing attentiveness while delivering drinks involves not just providing beverages but also ensuring that the overall experience for guests is pleasant and engaging. Replacing beverage napkins as needed and pre-bussing empty glassware demonstrates a high level of service and attention to detail.

By proactively attending to napkins and removing empty glasses, a server helps maintain a clean and organized table setting, which contributes to a more enjoyable dining experience. This action shows guests that their comfort and convenience are top priorities. When guests see that their server is attentive to small details, it enhances their perception of the service they are receiving and fosters a welcoming atmosphere.

The other options do not focus as effectively on the aspects of proactive service that create a sense of attentiveness. For example, asking guests to move straws themselves can come off as disengaging, while allowing guests to pour their own drinks can diminish the perceived attentiveness of the service provided by the staff. Each of these alternatives may not facilitate the same level of engagement and care that pre-bussing and replacing beverage napkins does in creating a polished dining experience.
