Why would the person who arrived second be interfering with the connector that is plugged into someone else's vehicle? There is no reason for anyone to do this.
Like most sub groups in life, there is a minuscule fraction of self-important Tesla owners who don’t care about anyone else and who will game the system to their advantage, even at others’ expense. Stealing priority on a paired cabinet is one such example.
That said, given the lack of detail from @viper2ko (like: “I saw the a-hole do it”, which would have been in the first post if that actually happened) it is extremely unlikely that this charging anomaly was actually the result of some kind of nefarious action. Far more likely it was a power blip or electronics reset or something of that nature, and this thread is just the result of misplaced frustration.
In 5+ years and 125k+ miles of ownership, I’ve had ‘charging interrupted’ a handful of times. Most during unpaired sessions.
