Excellence in Customer Service

In this day of “Excellence in Customer Service” where the customer is always right, should a business refuse to do business with toxic customers who continually abuse the staff and other members of the public? Should the staff have to put up with abuse out of fear as they may risk losing their job? I welcome your comments. http://notalwaysright.com/she-has-a-real-problem/24945
