What is a common method to remember customers' favorite drinks?

Keeping a personal log is an effective method for remembering customers' favorite drinks because it allows staff to document specific preferences, making it easier to provide personalized service in the future. This approach not only helps in recalling their favorite drinks but also builds rapport and shows customers that their preferences are valued.

By having a record, the service staff can refer to it during subsequent visits, ensuring a personalized experience that enhances customer satisfaction. Regularly updating this log as customers provide feedback or change their preferences can also improve service quality and foster loyalty, making customers feel recognized and appreciated.

Other methods may have their merits, but they do not offer the same level of reliability and efficiency in tracking preferences over time.
