Whatever happened to those little automated convenience stores people were talking up a few years ago? There was a startup called "Bodega".[1] Automated convenience stores the size of a shipping container were a thing in China, but they now seem to have one employee. There's "venhub.ai", but it comes across as a ploy to get VC funding, not a retail operator.[2]
Serving locations too small to staff, such as small apartment buildings, doesn't really pay. If you have fresh food items, the location has to be serviced at least once a day, and expired items must be discarded. Plus you're competing with Amazon and Doordash.
