The robot itself isn't really designed for shopping trips, as you can see by its lack of arms and ability to carry only very small loads (like, say, a breakfast pastry)--this one in particular is forced to use a hobo-like bindle. It also doesn't have any kind of e-commerce system like NFC, which would allow it to forgo the awkward, ambiance-killing need to tuck cash (cash! What year is this?) in its helmet for payment. Still, this is a whole new world for incredibly lazy people as well as legitimate teleconferencers, especially now that it's scone-compatible.
