>  automated convenience store

yes, interestingly, the butcher a couple houses down the road here was recently converted into a cashierless store: https://www.openstreetmap.org/node/5923097627

The tagging is much better, though: `self_checkout=only` is only an additional attribute and the `shop` key can still specify what goods are offered.

In that sense, the former "Späti" here could probably be better mapped as a `shop=kiosk` with an extra tag that indicates that there is only self-checkout in form of vending machines available. But `self_checkout=only` does not really fit and there is no other tag available.
