Pay for your past bills

A customer sent an order to a distributor for a large amount of goods totaling
a great deal of money.

The distributor noticed that the previous bill hadn't been paid. The
collections manager left a voice-mail for them saying, We can't ship your new
order until you pay for the last one.

The next day the collections manager received a collect phone call, Please
cancel the order. We can't wait that long.
