And that's the beauty of electric charging -- you actually CAN go do something else for that half hour, whereas with gas you have to stay in attendance of the pump (safety reasons).
Which means that you can top off your charge while at the grocery store, or work, or whatever.
There arent that many things you can do within half an hour at a charging station.
As someone who has used one, I disagree.
Tesla has tried to establish charging stations near shopping areas. There is generally lots to do. For example the last one I visited had multiple fast food places, an outlet mall and a casino. (This was in Primm, Nevada.)
It's a difference in magnitude that's the problem. For 5 minutes, of which half is spent actively interacting with the hose and payment, I can comfortably stand around. Anything more than that and I have to find something else to do while my car is occupied.
