What shop is suitable for opening at the entrance of the market?

Markets, especially farmers' markets, are places where people flow a lot. Many people go to the market to buy things or sell their own products. Especially in recent years, there are many clothes and businesses in the market, such as barber shops, breakfast shops, cake shops and convenience stores, which leads to a lot of people in the market. Many people go out without breakfast, and because rural people are well-off, it is common to have breakfast outside, so it should be a good choice to do business early.
