From John Scalzi Whatever:
At 7:07 I called Hertz and asked where my car was. They said I would have to call the O’Hare Hertz location directly and ask what the deal was, and gave me the number. I called the number, only to discover that if you don’t have the extension number of the specific person you want to reach, you can’t actually call the O’Hare Hertz location directly. So I called the reservation line and pointed out the problem of not having an extension. They said I would have to call the O’Hare Hertz and talk to them about that.
The next bit of dialogue is paraphrased but essentially true to the conversation that followed.
“So, you understand the part where I said that without a specific extension, I can’t actually reach anyone at the O’Hare Hertz, correct?” I asked.
“We don’t have any extensions to give you,” the Hertz person said. “You’ll have to call the local number.”
