What is the purpose of hand signals in the café?

The purpose of hand signals in the café is to streamline communications for drink orders. In a busy café environment, particularly during peak hours, verbal communication can become chaotic and difficult to manage due to noise and the need for quick service. Hand signals provide a clear, concise method for baristas to communicate essential information about drink orders, ensuring that everyone in the team is on the same page. This non-verbal form of communication enhances the workflow, reduces the chances of miscommunication, and allows for more efficient service, ultimately benefiting the customers.
