Well, then, don't do that

Me: "Doctor, it hurts when I do this."
Doctor: "Then don't do that!"

I need to invent an eye-rolling machine to save the countless millions who work with people who subject them to conversations like this one:

"Who do I send this to?"
"The bank."
"What bank?"
"The one that drew up the Agreement."
"That's a mortgage company."
"The mortgage company, then."
"But you said the bank."
"The mortgage company acts as a bank."
"But it's not a bank."
"Okay, it's not a bank."
"What bank should I send it to?"
"Uhhhh...the mortgage company."
"But you said to send it to the bank."
