Perhaps Luxembourg was the wrong choice. My point being, the present education system is centred around Thailand with the rest of the world almost completely blocked out. Questions are discouraged as it may show up the teacher as not knowing, thus losing face. Try showing a Thai worker a better way to do a job and you get, 'Oh! Yes, I see.' Then as soon as you turn your back they return to doing it their way, because that's the way they were shown by a fellow Thai.
Just one instance, I asked the electrician to install the light switches the opposite way up to their normal. The answer I got left me speechless. "Cannot, I have to twist wires, cannot." The mentality of a child doing a supposed tradesman's job.
