Which Professions Have the Most Loathsome People You've Met?

The key part is "you've met". Politicians are a given but most of us have only seen them on TV. I'm talking about people you interact with in your daily life. In what professions have you encountered the most loathsome, vile, dishonest people? (If you do have personal interactions with politicians, then that's an acceptable answer).

For me it's

Lawyers
Real Estate Agents
General Contractors
Auto Repair Mechanics

With each of these, the bad ones have outnumbered the good ones (but I have dealt with good ones, i.e ONE per category)

Cops are borderline, I'd say my experiences have been 50/50 good/bad.

Surprisingly, doctors are not on my list. I guess I've been lucky in that the doctors I've interacted with over the years, both for myself and family members, have been mostly good.
