This client may be someone who is purchasing from you because you are the only available provider of a certain language, or because you offer the best value. Respect them. You are doing business directly with the client now, not his or her business. Make that individual feel welcome; be friendly and polite. Make that client feel trusted by giving him or her decision-making power instead of just saying, “Well, you have no choice.” Always let your client know what is going on, and treat him or her as you would any other client.
