Small, rural White towns sometimes have this. I’ve never seen it in any large urban area full of strangers.
One thing I notice is that it’s mostly things that adults buy. Kids might want the TVs, but it’s not like an unstaffed store selling Pokemon cards.
Aside from that I give the Japanese a lot of credit for this.
I have seen "Honor" farm stands. They are getting fewer and fewer as the "diversity" finds them though... At least they are not targeted as often now that most of them switched to "digital" payments.
