If a customer feels like they are not being heard or understood, they may become agitated and defensive. It is important for businesses to clearly communicate with customers and make sure that their needs and concerns are being addressed in a timely and respectful manner. Some customers may also have attitudes due to external factors such as personal stress or frustration. It is important for businesses to be empathetic and understanding in these situations and to try to provide a calming and supportive environment for the customer.
