(I work at a public library. Patrons often ask us how to print from the computers.)

Patron: “I need to pay for my printing.”

Me: “Okay. When you hit the print button, how much did it say it was going to cost?”

Patron: “I did not hit the print button.”

Me: “What computer were you sitting at?”

Patron: *impatient* “I was not sitting at a computer. I am trying to print from the typewriter!”

Me: “I’m sorry, I am confused. You were not sitting at a computer, but at the typewriter? And you want to print what you typed?”

Patron: “This is ridiculous! I cannot believe you won’t help me!” *leaves*
