ZaZZZ will not steal product, either, nor allow customers to do so.
ZaZZZ involves two people touching the product. The employee loading it, whose name/number/where they sleep you know. And the buyer, whose ID will be confirmed as well. Pretty ironclad from a loss-prevention standpoint.
I've never worked a dispensary but I worked at a headshop in Houston for a couple years and caught customers and employees alike stealing, and that was with no actual cannabis products involved. That place hardly made money.
