Mary: "Hi, I need to get a copy of your insurance card."
Mrs. Paranoid: "I don't carry my card with me. Someone might steal it."
Mary: "Okay, but we need your information to bill your insurance."
Mrs. Paranoid: "I have Medicare."
Mary: "Okay, then can I get your Social Security number so we can bill them?"
Mrs. Paranoid: "I can't give you that. How do I know you won't still my identity, or sell it to someone who will?"
Mary: "We need some way of billing your insurance for the visit. Otherwise you'll have to pay cash today."
Mrs. Paranoid: "This is ridiculous that you treat people this way."
