This seems like a well-intentioned effort that is destined to fail, providing fodder for the "see EV's are a joke" bashers. People really need to think through the "use cases" for charging stations, not just install them for the sake of image. How does an L2 charging station at a drug store make sense? Maybe if you are really in a bind and didn't plan well.
Examples of "use cases" and benefits to the facility are:
-Airport parking: L1, the car will be parked a day or more, and L3 for people picking up/dropping off and the airport is a long trip
-Restaurant/Movie theater/Mall: L2, people will be there a while, benefit to facility is increased radius from which to draw customers
-Highway service plaza: L3 only
Plenty more you could think of, but Walgreens? Only L3 makes sense to me, maybe to offset the lost revenue from people no longer getting pictures developed.
