Cutting off the customer

The Wall Street Journal has an article that looks at how some companies are cutting off the customer that's costing the company more money than profit. Last year, many companies would work with their customers, offer them discounts or work with them on payment options. This year, however, many smaller companies are finding that by cutting off customers who don't pay actually increases their profit, as they have more time to spend with those customers who are making their payments.

Do you agree with this? Have you had to break relations with some of your needy customers in order to create a better supplier for your revenue-generating customers? How do you feel about this approach to business from a customer service perspective?
