A few years ago, I had the following conversation with a patient:
Patient's mother: "My daughter told me you told her X and Y."
Me: "Hmm. Well, I'm not sure I said that to her. Maybe she misunderstood."
Patient's mother: "You did! And I know you did, because she recorded you talking to her and played it for me!"
So that was horrifying. I don't know how many patients are actually secretly recording me, but it's not something I had ever considered before. I'm pretty sure it's illegal without my consent, a fact that I decided it was best not to bring up in this conversation.
Later, the patient apologized to me for recording me and was very embarrassed. She said she can't remember conversations unless she records them, so she records all doctors' conversations. Which is fine, but shouldn't she ask permission first???
