For Green Fresh Supermarket, sales would be relatively slow on the first day of opening. Business would only boom later. However, no matter how flat the sales were, things would be sold out before noon. Dry goods like rice and peanuts would be the exception.
Most of the customers on the first day were ordinary residents from nearby.
When a new store opened, everyone was curious, especially a supermarket that specialized in selling agricultural products. People would buy these things daily, so many would wander in to take a look. However, when they saw the prices of the stock, they would wander back out.
These vegetables weren't plated with gold or silver, so why should they be sold at such a high price?
Of course, the supermarket wouldn't force people to buy their stock. It was a free market.
