In some math problems, students often encounter rounding, especially when calculating the number of people. In real life, rounded cars will cause market instability in different scenarios.

Judging from the current situation, some merchants put forward promotional activities, but consumers found something fishy when they checked out. Originally, some checkout systems automatically rounded off, and some consumers spent a few cents more. Although consumers don't lack a few cents, fair and just payment methods will be conducive to market stability. Malicious erasure or rounding requires the consent of consumers.

Actually, there is another situation. Some merchants have not prepared a lot of small change, however, the price of some goods remains at around 78 cents. As a result, the merchant decided to change the change into lollipops or bubble gum. At this point, they will tell consumers that they lack change and can only use bubble gum or lollipop instead of change.

This behavior has touched the price law. When many netizens learned that merchants legislated for a dime, they expressed different views. Some netizens think that they have also encountered business rounding, but this will not affect their personal life. Some netizens think that merchants should complete the change of visa or collect the funds paid by users at the real price, instead of charging a few cents more without the user's knowledge.

On the other hand, the restaurant has apologized to consumers in the process. However, the apology has been unable to produce positive results, and the local authorities decided to file an investigation. At the same time, the "Price Law" is not in name only, and businesses should abide by the specific content.

To sum up, when there is a breach of contract in the whole industry, and the breach of contract will have an impact on the whole market, the relevant departments will adopt different schemes for the breach of contract in the market. The ultimate goal is clear, to protect consumers' rights and interests, to effectively urge major businesses to complete changes, and to reduce the overcharge of businesses.
