How should I calculate the money when traveling with friends?

How do you calculate the money when traveling with friends? There are mainly two methods.

The first method is for two people to implement the AA system. Before going on a business trip, first plan how much the trip will cost. Then the money will be divided equally according to the number of tourists, and each person will pay one share. One person in charge will keep all the money, and that person will be responsible for all travel expenses such as tickets, meals, attractions, etc. After the tour, the travel expenses will be paid. Settlement will be made and refunds will be made based on the number of employees.

However, some people may think this method is unfair, because some people eat more and use more, and the person in charge of the money may use the money unreasonably, resulting in excessive expenses. .

The second method is that you can first pay a part of the money to a person in charge. This part of the money will be used for expenses such as tickets, hotels, attraction tickets, etc. that have clear fixed costs, and then the rest will be used for food, clothing, etc. Personal expenses can be spent by oneself according to personal circumstances.

This method is relatively fair, and there are clear accounts for the use of the money handed over to the person in charge, so there will be no unreasonable use, and the use is relatively transparent.
