What professions give you a knee-jerk reaction to think 'scum bag' or scammer?
For me, I always had this kind of knee-jerk reaction to taxi drivers, used car salesmen, and, mostly in Bulgaria, real estate agents. In more recent times, I would add anything crypto-related to the list, too.
Car salesmen are probably the worst still I think. My uncle was importing and selling Japanese cars many moons ago, and the car salesmen he had on the lot were basically just criminals, constantly lying, stealing, and being shady af.
