Personally I've never run into this but -- a long queue would be fine, the car doesn't eat up much electricity idling. As for charger status, I mostly use the Electrify America app for finding a charging station (i get 2 years free with my car) and it's good for showing charger count and availability. So, if a charger was out of commission, it would just show 3/4 available. Google maps will actually show similar availability of various other company stations.
