Assuming this is Ecotricity, its the only place I can think of like this. I actively use the DC only charger so block the access to CCS while I am there. Their chargers aren't particularly reliable for CCS, but they are reliable for AC43. That means a Zoe owner can still charge while I am there, and they wouldn't be able to go to the next nearest charger if that was Instavolt for example, because no AC Rapid support. Of course a CCS car could still plug in to that type 2 at the one next to me too if they desperately needed the charge, where they can get just enough to continue to the next charger or plug in to the one I am using when I leave.
