If the supermarket starts spending more on labour/lost carts than they were losing with lost business/upfront cost, they may bring them back.
I wonder what the conversation is between supermarkets. They have to know the one spending upfront for these devices is training the local population reducing the other’s running costs.







A bit beyond the scope of the post. But instead of supermarkets using society to subsidise their labour costs, we could use supermarkets to subsidise society. Tax the wealth and institute a UBI.
