Damn right. I worked at a fish market for over a decade and there's a reason that jobs like active duty military and bomb defusal rank below all three of those jobs you listed on the scale of most stressful jobs. People are assholes day in and day out to these kinds of people who literally keep our society running and keep us alive.

Any time I've been in the hospital, my motto has always been "If crying, screaming, and pissing myself will help, let me know and I'll be the first to do so. But until then, it sounds like a whole lot of effort to make everybody's day worse."

I'd add tech support to that list. Cut my teeth there fresh out of school and it really taught me empathy towards service workers of all types. The crazy bullshit that people threw at me due to being stressed and irritated that their stuff isn't working was very eye-opening.
