Mr Sunday

There is said to be a Sunday shop. Everyone wonders why this store is called a Sunday store since it is open every day and there are no discounts on Sundays. People who went there later only told people who didn't know it because it was a black-hearted store. But it obviously cleared up the doubts about this store among people who didn't know it, so more and more people began to say that it was a shady store. So this black-hearted store became famous, no, it was this store called Sunday Store that became famous.
