How would you politely ask for a customer's name in Spanish?

The phrase "¿Me puede dar su nombre, por favor?" is a polite way to ask for a customer's name in Spanish, as it uses formal language appropriate in many customer service contexts. The inclusion of "por favor" at the end demonstrates respect and courtesy, which is essential when interacting with customers. This phrase also works effectively because it places the customer in a position of agency, which can create a more comfortable interaction.

Asking in the formal "usted" form shows respect, especially in situations where you are not on familiar terms with the customer. This makes the phrasing suitable for professional settings.

In contrast, the other options may not be as universally polite or applicable. For instance, while "¿Cuál es su nombre, por favor?" is also formal, it might come off as slightly more direct than option B, which softens the request with "me puede dar." The informal "¿Cómo te llamas?" is appropriate only in casual situations and not suitable for formal interactions. Lastly, "¿Está aquí con alguien?" does not directly ask for the name, making it irrelevant to the question at hand.
