Biggest mistakes most people make in Thailand is that they fall prey to the tourist traps in Bangkok. When it comes to dating Thai girls, look for other places besides the obvious choices (such as all the party / night life venues).
So here is a list of how things might go for you on a first date with a Thai Girl.
Remember Always that Thai people are unable to say NO.

I must have had over 300 first dates with Thai girls I either met off the internet or in person through friends and rarely do I ever go on a date with a girl I met at a nightclub or bar in Thailand (mostly cause of bad experiences).
Honestly they are incapable of it, even if they want to they won't, so if they don't like you, they won't be honest either so you need to read the signs lads.
