I always ask how much can you do this for - if they give a great price then thats the deal done, but if they're trying it on, I suck air through my teeth, just like a plumber would when you ask for a price in the west, and they clearly understand they've quoted too much. Following that the deal is usually about 30 seconds after this when they give you another price.
hmmm you won't be loaded but it's ok if you're not an habitual bar guy or massively into golf. If you're into bar girls, you've probably got about 18 months!
No anxiety for me, I've seen the tax bands, I've seen the allowances so have a rough idea of what it would mean for me and can afford it with no issues. Always good to be prepared and if it doesn't happen, I think there's a less than 1% chance they will drop it as it's aimed at rich thais rather than expats, then thats a bonus. But I'm set for it to happen, anyone not taking that approach will just have to deal with the fallout if/when it does.
