An update on my post from five years ago: https://paulsagemarketing.com/2013/12/11/no-more-waiting-at-the-deli-counter/
The kiosk is dead. Long live the kiosk. Self-service IS customer service.
Update, March 6, 2019: I think the new technology that Kroger has introduced, including online ordering (click and pick up) and scan-as-you-go, may have eclipsed the need for the old kiosk. But I still miss it.
