Of course, beer costs money, but you can't drink beer without eating anything. But the profits of barbecue and hot pot are really high. As long as customers can come, they should make some money. Let's not talk about whether beer is fake or not. In fact, I think since they attract customers for free, and in order to satisfy customers in the future, they will definitely not smash their own brands and get some fake beer to fool people. It is not worth the loss to damage their reputation. It can also be said that the more free things may be, the better, because they are for people to evaluate and think positively.
This buffet is similar in nature. Will you lose money when you meet an edible cafeteria? Actually, it's not. They are afraid that you won't come, not that you eat too much. If you eat too much, you will often come to attract others. Not everyone can eat and drink so much. Drinking beer usually takes a long time, and food will be consumed quickly after sitting for a long time. We can estimate the cost of these barbecue hot pot things, so it is difficult for us to hold a barbecue or hot pot at home, and how many things we ate only cost a little money. Their restaurants are all in bulk, so the cost will be lower and they are not afraid of losses.
