How did the Athenians respond to the demands of the Persians and how did the Spartans?

It is known that in the course of the Greco-Persian warriors, King Xerxes sent his ambassadors to various Greek cities with the demand that they bow before him and recognize the power of Persia. But Athens did not want to recognize Xerxes as their ruler and killed the ambassadors. In Sparta, the ambassadors were thrown into a deep well with the words “There you will find both land and water.”
