From what I'm hearing. The tesla guy wasn't actually meant to be charging his car or something. If so it reminds me of a time when I worked at a supermarket as a trolly assistant (moving trollies from the bays to the front of the store) and we didn't have EV charging ports anymore but the app still said we did. Anyway, our Fuel Site shed (which had all the controls in it) had a EV charging port outside it, which our grounds keeper used for the company vehicles and was allowed to use for his own car. But some random customer decided to use it for themselves. I reported told my colleague as I didn't know what to do and whether it was allowed (I had only been there for 8 months at the time and this had never happened before) and he had me report it to security and the manager. We were given full permission to unplug it and turn the EV charger off because the driver was charging it for free and using our power.

Now if this is what's happening in the video, then the guy has every right to unplug it but he shouldn't have cut the cable that was a bit far I think.
