It’s a smart move, to (try to) attract more upscale shoppers.
I’ll make the wild guess right now that they’ll spend more time shopping at Sam’s and more time charging at Walmart if just on a trip.
I don't know any "upscale shoppers" who shop at Walmart or Sam's Club and I highly doubt that more EV parking spots will change the demographics. Just more Woke crappola.
“(try to) attract more upscale shoppers.”
The upscale types will charge up the vehicle and enter the local Walmart for the first time.
Then they will see the rest of the shoppers....and run back to their vehicle!
