Why do people want to spend more expensive things when traveling?

Tourist attractions are relatively closed, either in urban areas or in remote rural areas, and tickets are charged. After people buy tickets, they can't go in and out at will. You can only come out after swimming, otherwise you will come out directly after going in, and the money will be wasted. A cursory look is not good. You need to take a closer look and take some photos as a souvenir. Especially in some big tourist attractions, some famous mountains and rivers, some ancient temples in deep mountains and some big Expo parks, tourists are easily tired, physically exhausted and thirsty. There are people selling sorbet and mineral water at this time. Does it meet people's needs? Of course it is. No matter how expensive it is, people will give generously. Outside the tourist attractions, an ice cream is one yuan, and in the scenic spots, an ice cream is three yuan; A bottle of mineral water outside the scenic spot is one yuan, and a bottle of mineral water inside the scenic spot is four yuan. Not to mention the prices of bread, biscuits, sausages, instant noodles and other foods, which are more expensive than those sold outside, and the prices have doubled, but people have no choice but to buy them. Buy less if you are reluctant to spend money, and buy more if you are willing to spend money. Vendors in scenic spots earn a lot of money, some actually set up stalls directly outside the Buddhist temple, and some put some food stalls halfway up the mountain, just where people are tired. This is a humanized management. The others are at the top of the mountain. When people are extremely tired, there happens to be food stalls and people are hungry. Of course, there are stalls on the Great Wall. In addition to taking the Great Wall Corridor as the business scope, it is also a good business to transform the beacon tower into a snack bar.
