What the regulations say doesn't matter a damn. What matters is what the guy in front of you at the immigration office says. If he says, "No!", you're stymied.
The administration in Bangkok is not going to bother with 'trivial' matters like this. It has given the local immigration offices carte blanche to make their own rules.... and if it wanted to tighten things up, it probably couldn't do so; the locals wouldn't stand for it.
I fully accept that we will have to continue to dance to whatever new tune immigration official choose to play.
Doesn't make it right though IB.
