Patron: Oop, almost gave you my credit card. That wouldn’t be helpful to you.
Me: I respectfully disagree, I think I’d find it pretty useful!
Patron: I think you’d need a little of my personal information before you could use it.
Me: What… is your opinion on having your identity stolen?
Patron: uhhhhh
Me: …by the cute library staff?
Patron: I… am against it.
Me: Drat!
Patron: But you are far more chivalrous than the average identity thief. I appreciate that.
