"thank you"

[Esther Kuntjara]

Dear All,
I'm collecting the expression of gratitude ("thank you") in different
languages. Please, tell me such expression in your language and how / when
it is usually used.
To give you an example, this is how "thank you" is expressed in
Indonesian:
"thank you" in Indonesian is "terima kasih" , literally means 'receive
love.' It is usually used :
-when receiving a gift / service / help
- after being given a chance to talk
- at the end of a speech / oration
- when refusing an offer
In reality, however, many Indonesians say 'terima kasih' non-verbally,
such as returning a gift given with another gift as a token of 'thank
you'. Some even refuse or show unwelcome attitude when someone says 'thank
you' after being helped. They think it's their obligation to help. The
expression 'terima kasih' could just mitigate the sincerity of the person
who helps.

Thanks for your help.
Esther
