A nice conversation guide, complete, without the line of what is expected of him, without more, but where Harraps (well rather the authors of the guide) is misguided is the transcription system used which completely ignores simply shades! For a tonal language such as Thai, where the tone can change the meaning of a word at all (MA = horse or dog, depending on the tone used), artlessly is recommended to the reader to listen to the Thais speak and he will come by himself to use the right colors. Outright scam or bad faith patent! I do not like this kind of choice that takes readers for fools and makes them believe that just jabbering with a big franchouillard accent to be understood.
