I've heard about this book. For me, I had some experience about this. Let me tell you. When I was in VN, I drove the motorcycle brand name is Wave Alpha which was imported from Thailand at that time and there were very few of them at that time. When I drove it on the street of Ly Thuong Kiet, one gentle man saw me and “hated” me. He did throw out the water from his mouth to my face and said in a bad language “D.M may, cho may bo cai thoi chay xe xin”. Oh god, I did not know what has happened to him? I did not know him and I did not do anything wrong. Another example is I used to wear hat when I was out and drove the motorcycle. If it was a windy day, then I lost my hat. Some days when I did a U-turn to pick up my hat on a street, two young gentle men was driving a Honda and laughing at me: “Your hat was with me, if you wanted it then followed me.” It was a terrible day for me. The hat was not costly and it was not belong to them. Why they took it? These are only the few things I can tell right now.
There are so many things to list about the bad habit of Vietnamese men. I can tell you some:
1) Say bad language when they open their mouth even they are well-educated and live in big cities.
2) Steal things from other people which any reasons. (both genders)
3) Drink too much alcohol and beer without stopping and become a drunker then drive motorcycle very fast.
4) Beat their wives and children with any reasons.
I cannot feel sorry for you with what you experienced in VN. Is there something wrong with you, guy? You called the brutes "gentle" and "well educated" when they humiliated and robbed you? For me, I think they are just scums. With what they did, it is not habits but criminals
