Due to the geographical location of Vietnam, there are many rivers in Vietnam, and many Vietnamese locals will trade on the rivers by boat. And some beautiful Vietnamese girls will attract some foreign male customers to buy things. At this time, they will put some lettuce on the boat. When they see some male customers, they always ask if they want lettuce. If the customer agrees out of curiosity, she will take you to some local teahouses or restaurants. Then they will sit you down, have some tea and tell you that she will get lettuce.
The result is often that they will never come back, and the tea you drink will be expensive. But you have to pay the bill again, otherwise the store will not let you go, so this is a very big pit, so everyone must pay attention. In fact, cheating is not only a way to sell lettuce, but also a lot of pits that will catch us off guard.
Therefore, when traveling abroad, we must be vigilant, control ourselves and guard against others. Otherwise, it will not only cost money, but also pose a threat to our personal safety. Therefore, when traveling abroad, especially in countries with poor public security, you must not blindly try new things, and you may be cheated if you are not careful.
