顾客用英语该怎么说

In English, a customer can be referred to as a "client" or a "patron." Both of these terms imply that the person is purchasing goods or services from a business or organization. For example, you might say "Our clients are very satisfied with the quality of our products" or "We appreciate the support of our patrons." It's also common to simply refer to someone as a "customer," as in "We value our customers and strive to provide excellent service."
