I have been living in Bangkok for a lot of the last 8 years. There are 3 things that continue to cause me stress and I don't think I will ever get used to them. I am sure I am not alone with these issues......I will list them for you - not in any particular order.
1. If you ask many Thai people a question about a procedure, or for directions, or anything really, and they do not know the answer, instead of saying they don't know they make the answer up ! This has obvious consquences, and really pisses me off.
2. Many Thai people will NOT ask questions of another Thai older than them or in a so called position of authority. I have been with many Thais in shopping malls who have even point blank refused to ask staff or a security guard directions or anything at all, only to spend ages struggling on alone to find somewhere or something. I could go on about this with numerous examples but won't.
3. Stupid farangs that think that THEIR bar girl is in love with them and is different to the rest.
The first two are to do with 'face' the last is due to I know not.
Ok, thats it - off my chest :)
