If you are currently working or have held a job in the recent past, imagine that you've encountered such a customer. if you don't have job experience to call on, imagine that you work in a retail location somewhere around campus or in your neighbourhood. identify the type of behavior this imaginary customer exhibits and the reasons the behavior can no longer be accepted. Write a brief email message to the customer to explain that you will no longer be able to accommodate him or her as a customer. Calmly explain why you have had to reach this difficult decision. Maintain a professional tone and keep your emotions in check.
