My initial reaction was "Wow, this woman is batshit" but then I thought about it and, damn it to hell, I am now conflicted. I mean I can see exactly how this is a case of disproportionate escalation, but at the same time if she was to remain passive or to go through the "proper channels," he would have kept on installing something she didn't want and by then she'd never get the old meter back.
Like I said, I'm conflicted, but I'm glad no one got hurt.
