<bot>: The best practices for dealing with a difficult customer include staying calm, listening to the customer, gathering all the facts of the situation, and responding in an understanding, patient, and professional manner. As much as possible, try to put yourself in the customer's shoes and work to identify what the underlying issue is and how best to address it. Attempt to resolve the customer's problem and acknowledge the customer's feelings and concerns. Ultimately, the goal should be to reach a mutually satisfactory solution.
