I'm not sure how such a prescriptive stance can help, but anyway....

I thought "hello" was the standard Thai greeting on the phone, just as it is in other languages. it comes up in all subtitled movies for phone scenes, whereas they do use "sawatdii" for hello as in good morning etc.

as for "thank you", I have repeatedly been told by Thais not to say "thank you" to waiters, cashiers, service staff. but why shouldn't I if the service I get is good? I don't look down on hard-working, smiling, honest people working in markets, restaurants, etc. it's of course different if you're treated rudely. but then, more is needed then a recommendation by some commission comprised of mummies (presumably!)
