What's really great is Walgreens has premiered their new Anti-Theft store design, where people have virtual kiosks they use to fill up a cart and buy stuff, and clerks will go grab the goods behind the counter and get them to the customer. AKA, what stores used to be in the early 1900's.
A renovated Walgreens store in downtown Chicago now only has two aisles of products available for public browsing while the rest is behind counters.

I see many large retailers in urban areas following suit.
