The major communication breakdown occurs because Thai folks don't listen to what is being said.

Their concentration span is extremely short & in general, they only listen to, at most, the first 3-5 seconds of a conversation, or instruction. Immediately after that, their 'can do' logic kicks in & they move off to do what they think they heard.

Invariably, they haven't taken in the full instruction & end up doing the wrong thing.

Thereafter, the save face concept kicks in as a self-preservation mechanism, followed by it's your fault syndrome.

This is a common problem trying to transfer technology to Thais - it is simply impossible! I refer to it as the concrete in head syndrome.
