What action must be taken before presenting the check to a customer?

To present the check to a customer properly, it is essential to fully bus the table and check the bill beforehand. This ensures a clean and orderly dining environment, which is conducive to a positive customer experience. Busing the table involves clearing any used dishes and utensils, which not only makes the table more inviting but also reflects well on the service quality. Additionally, checking the bill ensures that all items ordered are accurately charged, preventing any discrepancies that could lead to confusion or dissatisfaction when the bill is presented. This attention to detail demonstrates professionalism and respect for the customer, ultimately enhancing their overall experience at the establishment.
