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 voicemail 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."

Bank customer service
"I'm not saying that the customer service in my bank is bad, but when I went in the other day and asked the clerk to check my balance ... she leaned over and pushed me."
