Anyone who serves the same public for years builds an ear for the polite version of a question. Customers ask about size when they mean price, about availability when they mean whether they are welcome, about how something works when they are worried about looking foolish. None of that is deception; it is how people protect themselves while asking, and recognising it is a skill made of thousands of repetitions rather than insight.

Consider what your own habitual polite question is, the one you ask instead of the real one. And when you are the one being asked, let familiarity make you generous rather than knowing.
