I've been here nearly 16 years now and quite a few years back I was asked if I would be interested in teaching in a Thai technical college, my simple answer was, NO, because you can't teach a Thai anything, especially if you are a Falang.
I did some renovations here a few years ago that required a sloping fence top to be cut off and a new top put on it, I told the guys doing it I want a 10mm slope put across the top of it, they argued with me that it wasn't the way "They" do it, I simply told them I was paying and I wanted it done my way.
When the same guys came back and saw why I had asked them to do that, they said, Oh mister you very smart, we would never have done that. It was there, so I could fit a flashing on top of the fence so the rain would drain off it.
