He specifically knew that the charger wasn’t directly compatible, he ordered an amazon adapter (which didn’t work) specifically to make it work.

Then he went to another charging location that did work, so there was already a solution to his problem. Just not the one he wanted.

He even states that his problem is that he’s impatient, Rivian was going to send an adapter out but because he got his car recently he’d have to wait longer.

While he’s not the worst person in the world… I’d still say it’s good odds that he’s an asshole.
