That's called a passive-aggressive response. This dude was a total tool who expected a pass because he's gotten away with it all this time. His 'I'm playing with you' is his standard cop-out, and I've heard that BS more than I care to, and no longer tolerate such high school behavior.

I imagine he's got some whiney-azzed post of outrage about 'his rights' posted out on his social media somewhere. 

Good for ASA.
