It's probably true a lot of upper-middle class people now would prefer to charge while getting some shopping in - but presumably in the future people will just want convenience. I could see a chain like Costco or Target adding EV stations to every parking lot - but I think for the most part gas stations are located where the cars are.
(Also, the scale of this seems good and a good way to make investors feel good about a hedge, but that's beside the initial point)
Very few are going to need charging when doing a shopping run. So why not just charge at home?
Those not having a good over-night or at-work charging on the other hand I do understand. But how many that don't have either of that can and will buy an EV in the first place?

In time, maybe, yes. But I don't think the deciding factor for these people (myself included) are charging stations at the mall.
For one, it'll probably cost the same as for existing retail stores to install charging points. But all existing retail stores have the extra benefit of saving you time while you shop, do laundry, get your hair done, etc.
