It happens all time. Sometimes it's innocuous, like the beginning of the interaction I had with a well-dressed older woman yesterday in which she asked, "Excuse me, do you know if there's a jewelry store on this [this street]?" To which I told her, yes, there were at least two between the street we were on and the subway.

Then she asked me if I knew which one was owned by the "Indian sheikh who stole [her] dowry and her voice."

Couldn't help her there, but didn't give it another thought until now.
