Haha, yes indeed. In a way it's a form of mild karma, they got fed, but my dad certainly took up a lot of their time that's for sure. He has a habit of doing this with a lot of people he meets. I should really share the story of the time someone came to the door selling paintings (you know those people), he was a backpacker from France trying to make a little money doing door-to-door canvas painting sales. My dad fed him as well, but it was chicken flavoured two-minute noodles. And my dad managed to get a bunch of free canvas picture samples, which they don't usually give out.
