Stopped to charge Tesla on long journey from England to Scotland in awful weather, having found the usual chargers at Gretna were closed for refurbishment. App said 15 out of 16 stalls were free - hurrah, as we were down to 7%. One stall was indeed filled by a Tesla charging up. The majority of the others were also full, due to non-electric cars parked up in the hotel car park for the night. Mentioned it in reception while charging, and they said it was because they had an event on. Won’t risk it again, as management of the electric charging points was non-existent, felt lucky to find a free one.
