Everyone should have eaten the buffet. You can eat as much as you want. Too many leftovers may deduct your money, so most people will dispose of them secretly in the end. Some are put in hot pot, and some are just bagged to take away. This situation is not uncommon. It may be fine not to be found, but it will be embarrassing to be found. This is the mode of eating in the canteen. Sometimes the hotel also provides a buffet breakfast. They will provide many kinds of things. You can choose what you like, but you must finish what you choose, otherwise it will be wasted. Some people secretly put eggs, cakes and fruits into their bags after breakfast. This is unreasonable. Don't do this.
There are clear rules in the restaurant. The breakfast you choose must be eaten in the restaurant and cannot be taken away without permission. Someone gave you a breakfast coupon, so we can only eat with this breakfast coupon. Since everyone is here, we must abide by other people's rules. Some people say I took it because I couldn't finish it. In this case, we can actually understand and hope that the restaurant will not be too serious, otherwise this thing will really be wasted.
Sometimes it's really not cost-effective to eat buffet. Everyone wants fifty or sixty dollars, but they don't feel as much as they usually eat. Everyone has a psychology that is not very cost-effective, so they will sneak this thing into their pockets. Please don't do this, there is no need to influence others' views on yourself in order to save a little money.
