I was purchasing services and goods over the phone.
The saleswoman wanted to make sure that the identity I used was truly mine.
So, after I gave her my address (I live on 63rd Street) and credit card number, she tested my familiarity with the neighborhood I claimed to live in by asking:
"Can you name a street close to 63rd Street?"
"62nd Street", I replied.
She concluded the transaction with a professional: "Thanks, and have a good day."
