As a professional, but not a building trade, I think the thing in my field which bothers me the most is when I perform a procedure on a patient, it goes flawlessly, patient doesn’t feel a thing, takes 5 minutes, then they get upset at the bill. I had one guy griping about the ‘thousands of $ an hour’ I was making. I told him, “You didn’t just pay for 5 min of my time. You paid for 16 years of education after Highschool, no sleep nights, 20yrs of real world experience, a building, nurses, and office staff. Would you rather have remained in extreme pain and had another doctor take an hour, fumbling his way through it for a cheaper price?”
