Your date wants her friends and family to check you out and will ask what they think about you later when they are alone.
This is kind of like a job interview in front of board members.
If you make the right purchase she will know you know how to spend your money wisely.
She will never marry a man who throws money away or a man that has no money or is cheap.
Girls that work in bars are for having fun in the short term and that is as far as it goes.
Both Thai men and women know this but for some strange reason many male visitors to Thailand just don't get it. Many people who have met my wife and I ask where I found such a wonderful person, well it wasn't easy. The best place to meet someone is where she works (not a bar).
We then looked at medium price watches and she found one she liked and made the purchase. If a Thai girl convinces you to make an expensive purchase when it is not necessary she thinks you spend way too much money.
If you make a cheap purchase she will think you are stingy.It is OK for the lady to put her arm and hand around the man's arm but that's about as far as it should go. If a girl lets a man touch, hold hands or put his arm around her the Thais believe the girl is easy, loose or maybe a prostitute.If you look at the way girls act in the bars it is easy to understand that any traditional, well educated Thai girl would not want to be seen as such a person.Thais are very thrifty when it comes to spending money, they know how to get the most for the Thai Baht and she is looking to see if you are the same.Suggest Pizza Hut for the "all you can eat night" is a very good bargain and she will take notice of this.The first thing to remember is that girls can touch the guys but the guys CANNOT touch the girls.
