Common request at a bar

The crossword clue refers to a common request or phrase that is often heard at a bar. The phrase is “Can I see some ID?” which is typically asked by bartenders or servers to customers who are ordering alcoholic beverages. This request is made in order to confirm the age of the customer and ensure that they are of legal drinking age. It is a common and necessary practice in bars and other establishments where alcohol is served to avoid the sale of alcohol to minors or other individuals who are not authorized to purchase it.
