So I stopped twice to charge today. Once in parry sound and once in Sudbury. In both cases I was the only one there. In parry sound I was billed a portion at 20cents per minute and then a portion at 40 cents. In Sudbury I was charged 40 cents the entire time. My understanding was 20 cents was until you reached a certain state of charge and after that it switched to 40 cents. In Sudbury I arrived with less than 20% remaining and was billed 40 cents for the entire 15 mins I was there. What am I missing?
