There are times when a customer is more trouble than they are worth and you no longer want them to buy from your business. But you don't just say "You're Fired" but make the split as smooth as possible for both sides. Here are some reasons why you may want to say goodbye.

.Finds something wrong with every transaction
.Doesn't see any value in your products or services
.Doesn't appreciate any extra effort you offer them
.Is rude or disrespectful to your staff
.Tries to argue for a lower payment after the delivery
.Keeps threatening to take their business elsewhere

.Asks for something free with every order
