I work in a phone store. A aunt recently came to us, waited for a long time and finally approached me and asked, "Do you have Nothing?" I say: "No, we are trading on phones." She answers me: "So I need the threads to ask for the phone". In a state close to hysteria, I explain that the phone is not threaded. She didn't seem to believe me and, leaving, said: "That's how I knew that there was no bullshit, even no phone lines."
