A merchant sent an order to a distributor for a large amount of goods totaling a great deal of money.
The distributor, noting that the previous bill hadn't been paid, told the collections manager to check it. 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."
