"Hello? Is this the technical support hotline?"
"Yes, this is Carl speaking. How may I help you today?"
"I think my diskettes are faulty. I keep getting the error message bad or invalid disk operation"
"I can help you, but I will need a copy of your defective diskettes to help me diagnose the problem. Could you send a copy to our customer care centre?"
A few days later, a package arrived for Carl from the customer. The package contained several photocopied pages, they were copies of the diskettes.
