^^^ Yes. That is how a normal person would respond to the request to use SoberLink. SoberLink even markets itself as a way to build up a track record of sobriety which the monitored party can use - not just as a way to "catch" someone drinking. If he's stomping and snorting about not wanting to be monitored, to me that suggests that this is all about power and control and not wanting someone to tell him what he can or can't do (i.e. drink).
If he stopped and thought for a moment, he would see that SoberLink is actually a tool that he could use to his benefit in order to leverage more time with his kids. But he is not stopping and thinking because he's using alcoholic brain.
