" Your Plan B may seem like an imposed consequence since it is you who are the key actor. But remember what your Plan B is—your best alternative should the other refuse to respect your interests. It is not a punishment for the other, but simply the logical path for you to follow in pursuit of your legitimate needs. It is an alternative path to success. Let your Plan B speak for itself. Through your quiet tone and confidence, let the other know you are serious about carrying out your Plan B with its attendant logical consequences. "
