Such a nice experience!
The agency I work for did a website for Franciscan nuns a few months back. Today three of the sisters brought us a lunch they made themselves: a hot dish, rice, and bread---even Franciscan wine. They gave us each a keychain with St. Francis on it. We've had clients send lunch in to us before as a thank-you---but we never had clients who personally MADE us lunch before and brought it to us. I enjoyed meeting the sisters.
That sure is a very nice way to say Thank you to someone~:-D
