What is the purpose of a serviette in bartending?

A serviette in bartending primarily serves the purpose of enhancing customer comfort. It provides patrons with a means to manage spills, wipe their hands, or clean their mouths while enjoying their drinks, which contributes to a more pleasant experience at the bar. By having serviettes readily available, bartenders ensure that guests can maintain hygiene and comfort while consuming beverages, especially those that may be messy or require the use of hands.

While the other roles of a serviette, such as serving drinks or decorative purposes, may hold some significance, the focus is largely on customer comfort and convenience in facilitating a satisfactory bar experience.
