Yesterday, on my way home, a bit after 6 pm, I poked my head into a new restaurant nearby and asked the proprietor: "Are you open for lunch?"
I was thinking about the lunches with speakers that we have at our Tax Policy Colloquium.
He said no, but with an odd tone, as if he resented or disliked the question. So when I got home, I checked the restaurant's website, and it turned out that they are open daily from 11 am on.
I think he may have interpreted my question differently than I meant it.
