First time I see a menu that's comparable to a filesystem tree I'm going to burst out in laughter and think it's a gimmick. A supermarket is closer to an art statement about inherent chaos of modern lives than to anything hierarchical. Yes, there are hierarchical systems, the big one being a common management structure (which works eh), and administrative subdivision of countries (hint: people almost never actually traverse that tree, they always go directly for a specific entity in it. Also, they routinely get lost in it). They're a bother and used when they can't be avoided, or when nobody bothered to work on something better. Or when you need to sort a bunch of numbers or something. The reason for avoidance being, besides the low transparency, complex data maps into trees really poorly.
