I'm delighted you've had positive experiences. I'm really very happy for you, that's wonderful.
I'm not bashing the controllers, that's an unfair characterization. I'm not saying they're bad people, I'm saying they're human and like all humans they respond to incentive. Everyone responds to incentives, that's how all creatures operate every day.
It's very simple. At an airport funded by government taxation, the salaries and job retention of everyone involved do not require and are not contingent upon how happy the pilots are with the service. Therefore there is no incentive to please the pilots. That's it. It's not bashing, it's not rocket science, it's just basic logic and humanity.
This is why you get better service at Walmart than you do at the DMV.
