How do you pre-authorize a credit card for a guest?

To effectively pre-authorize a credit card for a guest, opening a tab and sliding the card before ringing anything in is the most appropriate method. This process establishes a credit hold on the card, allowing the server to ensure that the guest has the means to pay for their charges before any transactions take place.

By sliding the card at the beginning, you not only protect the establishment from potential non-payment but also streamline the payment process for the guest. This approach allows the guest to order freely without the immediate concern of payment at each step and helps in managing their total more efficiently as they enjoy their dining experience.

Options that suggest charging at the end of the meal, requesting payment before serving, or swiping the card after the meal do not establish a pre-authorization effectively, as they either do not confirm the availability of funds until after the meal or create unnecessary friction in the service experience.
