I opened a revolving sushi restaurant less than a month ago, and business has been bad in recent days.

For example, it is normal for any restaurant to have a decline or fluctuation in its operating conditions within one month after its opening, but we should be alert to whether this decline in turnover is persistent or unstable, high or low. Whether there is any promotion and marketing activity before opening a store directly determines the operation of opening a store, and the promotion of opening a store is necessary.
