Because all the ingredients in the buffet are bought in large quantities, they are very cheap, and there is less manual use, and one person can't eat much. So although 51 yuan is the only one, the buffet can't be eaten. With the development of society and economy, everyone is rich now. Money bags have swollen people's dining tables and great changes have taken place, and buffets have emerged. Because the buffet is very affordable and cheap, and the ingredients are particularly rich, it has won the love and favor of many people. First of all, the source of buffet raw materials is very cheap. The raw materials of the buffet are purchased in large quantities, and many of them are directly purchased from manufacturers, so in this case, they will get these ingredients at a very low price, so their cost is very low. Secondly, there will be fewer workers in the buffet. Compared with other restaurants, it needs a huge kitchen system, many chefs and many kitchen staff. But for the buffet, there is no such complicated kitchen system, only a few people or no chefs are needed, which saves a lot of human resources costs in this respect, so it indirectly reduces the cost of opening a buffet. Finally, in fact, each of us can't eat much at the buffet restaurant. Although there are only 51 people in the buffet, we really can't eat much in the cafeteria. Because the buffet restaurant has very rich ingredients, a lot of varieties, including fruit, meat, vegetables, all kinds of cooking, drinks and so on. If we eat a little of everything, we will be full if we don't eat much. Especially if you drink those drinks, it is very easy to make people feel full. So it seems that there are only 51 people in the buffet, but the boss will not lose money, and will make a lot of money.
