I sometimes work with technical support for PC's. Mostly it is people that have just bought their first PC and want me to configure Internet, install a printer, and such.
But this one client came to me with a complaint. He had just bought a cheap PC which came with Linux and complained that "the Internet does not work in that ****** Linux thing!".
Since I use Linux almost every day, I decided to check. The modem or network card might not be configured. I configured it.
Me: "OK, now try to open a web page".
Him: "See? It does not work"
Then I realized that he didn't even have a phone line, only a cellphone. So he couldn't have neither dial-up nor DSL access, and cable was not available in his area.
Me: "Do you have an Internet connection?"
Him: "No, but the salesman told me it came with the Internet!"
