According to customer service best practices, which is a key attitude that a bartender should maintain?

Maintaining a friendly and polite demeanor is essential in bartending as it directly influences the overall customer experience. A bartender's attitude can create a welcoming atmosphere, encouraging customers to feel comfortable and valued. This approach fosters positive interactions, making customers more likely to engage in conversation, place additional orders, and return in the future.

A friendly demeanor helps to build rapport with patrons and can lead to better tips and customer satisfaction, which are critical for success in the hospitality industry. In contrast to the other choices, which either suggest a lack of engagement or focus entirely on the technical aspects of bartending, a friendly and polite approach that emphasizes interpersonal connections enhances service quality and promotes repeat business.
