My Model S is currently with the service centre in Toronto due to an issue I recently had. They won't be able to work on my car until Tuesday or Wednesday, so I assumed they would leave it in the lot until then (it had around 55%). However, they kept it connected to the supercharger since Saturday. I feel terrible that the car is plugged for the entire weekend, so I left a note on PlugShare. I'm not sure why they would do that, especially in a super busy supercharger like Lawrance.
