In the ER, as an intern:
Me: "How much alcohol do you drink?
Patient: "I drink beer at night."
Me: "How many beers?"
Patient: "You know, a couple."
Me: "Well, how many? Like 2 or 3? 3 or 4?"
Patient: "Um, I'm not sure..."
Me: "If you had to take a guess though... how many beers a night?"
Patient: "Maybe 5 or 6."
Me: "Okay. Have you ever wanted to cut down?"
Patient: "You know, these questions are a violation of privacy."
Me: "Excuse me?"
Patient: "I mean, you're asking me 2 or 3, 3 or 4 beers... I feel like this is rehashing prohibition."
Patient: "Well, I guess you don't know much about American history. Prohibition was... look, I don't mean to lecture you. It just feels like... you know, there are some questions that are private that you're not supposed to ask."
Me: "I don't want you to feel like I'm singling you out. I have to ask everyone about their alcohol use. It's on the form and I have to fill something in. I don't want you to feel like I'm attacking you."
Pt: "No, I'm sorry... I just... I feel like some things ought to be private, you know?"
Me: "Yes, of course."
I wrote on his history: Patient became very defensive when asked about alcohol use.
