I don't think this would be a viable business model, but that is just my opinion.
With the limited range of most total electric cars that I am aware of, the person would most likely already be in the general area anyway.
And if there are already pinball machines or some arcade in that area, that person would already be aware of where the best places to go are located, if they wanted to play pinball while the car was charging. They could just uber to those existing locations from the charging station, if they had that much interest. Plus, most of the places that I have seen with charging stations are generally unoccupied, from what I have seen anyway. It's not like there is a huge wave of electric cars coming from all directions to charging stations, waiting for their turn to get charged back up. Gas stations with a few cents of savings seem to have a lot more traffic and people waiting to get the pumps.
