First ran into these locking carts at Kroger grocery stores here in Georgia years ago. I often wonder at the lost productivity of unlocking malfunctioning carts (if they unlock) and what the frustration for customers does to sales. I haven’t noticed them at Publix (where they say shopping is a pleasure). Not thrilled if Target has them now. It’s a bean counter solution to theft that doesn’t work seemlessly.
I wouldn’t know about Target. I don’t go in there. It is up there with Starbucks as places I will not enter.
There’s a Publix in Seminole Heights in Tampa that uses them.
They do stop abruptly. I’ve watched it in action.
