During the trip, others asked you to help with the purchase, would you agree?

It depends. If it's convenient, or if it doesn't take too much time, I will help buy it, but if it's too hard, it may not work, and I will tell people in advance that it's a random purchase, and everyone will reach an agreement with each other.

In a foreign country, the biggest problem is that you are a stranger. After all, you are not a professional purchasing agent, and the travel distance is usually tight. If one or two people have to go shopping at this time, it will take a long time. It is very likely that you will not play well in the end and come back with a lot of trivial things. In this case, you will simply forget the original intention of traveling.

If you want to buy, the most important thing is to tell you the truth before you buy. Everyone has the knowledge of purchasing with fate, and you are not sure whether you can buy it. I remember one time, a friend of mine went out for a trip, and another friend asked him to bring something. As a result, the friend packed the ticket with confidence and said that he wanted to buy it. When he came back, he didn't get it because of the itinerary. The other party has been full of expectations, but when the journey ends, they find that they can't get what they want. The atmosphere between two people was wrong immediately, and then he gradually alienated, and two close friends became strangers. What a pity.

Finally, look at people and don't buy them for people who are particularly picky. As long as such a person is slightly less than what he wants, or the price of something he buys is slightly higher than his expectation, he will repeatedly question you and suspect that there is a price difference between you, so in this case, you must keep your eyes open and don't waste energy on such a person.
