But in Silicon Valley, combining laptops and shopping carts is just a way to get chores done. When at Whole Foods in Los Altos, I saw a man pushing a shopping cart with a laptop in the part where you can sit your toddler. I suppose he was reading a recipe or something. (I, and I’m sure other Valley folks, do that on a phone.)
A bit odd, but then again, I used to be (I’ve fallen off a bit) judicious about capturing the contents of my shopping cart with ZoneTag.
