They should sell...

[Juniper]

You know what I wanna see? This isn't a product you can buy, but you use it for buying stuff -- I want grocery carts with locking wheels. You know how it is, your grocery parking lot is on a slope, so you gotta hang onto the cart with one hand while opening the car trunk with the other, and if you dare let go . . . runaway cart! Or else it bangs into your car. If they can do it for baby strollers, why can't they do it for grocery carts? They're basically glorified baby strollers anyhow. Seems pretty obvious to me.
