Most any federal criminal investigator you speak with will have had it. It's useful EVERY DAY... whether we are talking to people at work, dealing with your children, "dancing" with a motorcycle salesman (a few months ago in my case), or just (innocently) screwing with people at the bar.
It's a good skill to have in everyday life. However, sometimes it is fun to just ignore what you have learned in the class and just use brute force... but that is just my opinion.
We bring evil things to evil people, kicking in a door near you!

"The difference between 'involvement' and 'commitment' is like
an eggs-and-ham breakfast: the chicken was 'involved' - the pig
was'committed'."
