It all depends on the woman’s background – don’t take her to places she might feel uncomfortable or dislike.
Your date is probably just as nervous as you are, if not more!
Make sure to make the girl aware that she can relax and act herself too.
Try and remember things she’s already mentioned or stuff you’ve already talked about.
If nothing, you can ask your lovely lady questions about herself and things she is interested in.
Avoid any unintended insult or avoid negative comments about country.
If you’re not sure she’ll be offended by what you’re about to say, best not say anything.
Again this doesn’t mean that she doesn’t like you but simply a case of “the wrong place at the wrong time”. This gives Thai women a bad impression and will make your date think you don’t care enough about her to bother showing up on time.
You could show up early but not too early as your date might be putting on her makeup or getting ready and Thai women very sensitive about their looks, especially on the first date.
Continuing on the above, most Thais are very religious and have deep spiritual beliefs.
