I kind of take issue with the fact that this works, maybe not in your foreign language example but in general. I shouldn't have to learn the terminology of HVAC services or plumbing services or any service that I have no intention of learning more about to get better service. Every customer regardless of their knowledge of the service they are using should get a competent response without having to learn anything about that profession. That is the whole point of having a professional there working for you afterall.
