Yes and no. I returned to my car and someone had unplugged the CCS connector. On challenging the person he said the charger had finished. Checking my vehicle it reported 95% which is as much as it can do on a rapid charger. It seems that once the vehicle is charged it unlocks the CCS.
To answer the poll. I’m happy for someone to unplug my car when charger is finished. And I would risk unplugging someone elses if fully charged. Only fair in my book. However I wouldn’t touch the charger flap, some cars have little electric motors to open and close these so wouldn’t want to break that. Assume other People wont close the flap, and remember to check it is closed. (Yes I have driven off with it open
).
