Oooooh Dear
(A customer calls, wondering about his online order that he has placed. I ask him for his order number, but he can’t seem to find it.)
Me: “Your order number will be the number on your packing slip that starts with five zeros.”
Customer: “Oh, I see that now. Do you want me to read off the five zeros, or do you already have that?”
Me: “I already have that.”
