I work in the technical support department for a national ISP. One day, I was listening to the conversation of a tech next to me talking to a very frustrated woman. Apparently she had been having trouble getting online with our software, and the previous tech had her go into Dial-up Networking to create a new connection and get her online, so she could then download our software. That, amazingly, had been successful, but she was calling back to complain that when she had finished downloading the software and opened the CDROM drive, there was nothing in there.
The tech replied, in his thick Australian accent, “Ma’am, this is not a vending machine.”
