> and how that would vary when in a metropolitan area such as SF. I've spoken with grocery store clerks in SF (at major chains like Walgreens) who were concerned that their stores might be closed because of truly excessive losses due to constant shoplifting. Of course the shrinkage is factored into the price, but you can only raise prices so much before it starts eating into your sales. BTW, when I visited the Amazon Go in SF it actually seemed to have more staff present than a regular grocery store of comparable size.
