40 minutes at a charging station?
Hmmm ... that represents a temporarily trapped consumer market ... could sell many knick-knacks to folks in that time ... Slim Jims, cigarettes, Juggs Magazine, Trojan Enz, energy drinks, Strip Club BBQ ...
How long does a normal consumer spend at a gas station during a standard refueling? Not 40 minutes. There's an opportunity to further fleece those suckers.
