Meanwhile in Tokyo you have self serve 24/7 convenience stores. And I’m not talking about vending machines. This is where you grab the item, enter on a screen what you got, pay for it, and walk out. No staff needed.
Petty theft does occur in Tokyo, and there's organized crime as well. You don't see this kind of organized retail theft because the police would actually investigate it, rather than do nothing and cry about "the crackdown on police rights".
