The grocery stores on the streets face greater competition than chain convenience stores. According to studying data, nearly 60% of grocery stores have 3 to 5 competitor within one kilometer, but the main products they sell are snacks, beverages, drinks, and daily necessities.
Grocery store operations face a more competitive environment. In terms of customer flow distribution and main categories, more than 60% of the grocery stores' business starts at 6:00 pm, and 61.4% of the business is carried out at night, more than half of the grocery stores have their most customers at night.
Some grocery stores are open 24 hours a day.
After three o'clock in the morning, the customer flow will gradually decrease. There is a lot to do in a convenience store. The supplier will come to deliver the goods, and the grocery stores will be responsible for receiving the goods, arranging the shelves, and loading the goods, cleaning the fresh food machines, cleaning and sanitation in the store. At about four o'clock, it is time to start preparing the fresh food to be served the next morning: soy milk, tea eggs, steamed buns, fried dough sticks, corn, sausages, porridge, and so on. So working a night shift at a convenience store is no easier than working a day shift, and they hardly have any free time. They have a lot of work to do, which cannot be done during the day because after all, there are many customers and a large flow of people during the day. Doing these tasks will affect customers' shopping and reduce the shopping experience.
