(I am helping a customer become familiar with his new product by showing him how to turn it on and off.)

Me: “If you press and hold the button on the top right hand corner of the device, you’ll see an icon on the screen that you can slide to turn it off.”

Customer: “Oh. I thought they would have an app for that.”

Me: “What do you mean?”

Customer: “They have apps for everything else, so why not for turning it off? That seems silly.”

Me: “Well, how would you turn it back on if it’s off and you can’t use the screen to get apps?”

Customer: “Oh… well, I thought it was clever!”
