One subway in Japan is performing such personal gardening, growing their own hydroponic lettuce right inside the store. It’s not enough to meet customer demands, topping just 5 per cent (if that) of all the sandwiches served at that location. But to be fair, Subway puts a truckload of lettuce on every sandwich. As in, lettuce is actually the first entry on the ingredient list for the BMT.* [Subway via MSN via AsiaJin via InventorSpot via OhGizmo!]
*This isn’t true. At least, I don’t think it’s true. But it could be true. You believed it for a split-second, yourself. And that alone is all the proof I need.
