Some of Athena's many advice to meeting new races;
One-- Always learn their culture before making any dramatic encounters; if not possible, then have a liaison that would guide you throughout the new world.
Two-- Never put yourself in a position that would warrant the attention of more than 3 people; that number is all it takes for rumors to spark around your existence.
Three-- Avoid the world's police force as much as possible.
Four-- Probably don't take a member of a Royal family hostage.
