A movie character (not main) idea.

An old man with white hair and semi-big white beard. He goes to supermarkets and pats on strangers shoulders, saying “Hm..you’re thinking” and say what menus and activites these strangers were thinking of doing with these ingrediants — and he’s always right no matter how radom the items seem.

I wanted to meet that kind of old man when I was at a supermarket yesterday.
