The failure of the Grocery store self-checkouts is that they are not automated enough. The customer still has to manually scan every item. Items have to be placed one-by-one in the bagging area. Any small divergence from this, or something out of the ordinary like an Alcohol purchase triggers an exception and requires human intervention. This is enough automation/tech to be annoying but not enough to solve the real problem. Contrast that with the Amazon Go store which is automated enough that very few would prefer the cashier route even if available.
