Suppose a librarian receives an email from a man named Greg Walsh, wanting to become a cardholder or simply inquiring about the open hours. Would the librarian reply? And, if so, would the reply be polite, including for instance some form of salutation, such as “Hello” or “Good morning”? Does your answer change if the guy is called Tyrone Washington? Is a librarian treating Jake Mueller differently from DeShawn Jackson?
