I don't thnk so. To do that the business owner would want to ensure that only their customers charged at the Supercharger location at their store. Not feasible.
That article includes this quote:
John Brehm, Hy-Vee director of site planning, said about the deal (via
The Gazette):
“The time it takes for an average shopper to get through a grocery store to get groceries is about the same time it takes to get a full charge on a decent fast charger like this. So it’s a marriage made in heaven.”

Which brings up another point. The Supercharger network is, in my opinion, inexorably moving away from the original purpose of providing charging primarily for long distance travel and towards a more mixed use network, charging for long distance and local and even somewhat business-specific sites.
Think about the Tesla owners that Hy-Vee is trying to attract. They are ALL locals. Few people drive over 200 miles rondtrip for groceries (Yes a tiny number do, the vast majority do not).
the recent Supercharger announcement is clearly intended to address that issue, as is the ontological mg buildout of the network.
