August and October. According to the query of Kyushu Drunk Catering Network, the off-season of fried chicken shops is in August and October. When the weather is hottest or coldest, it is mainly affected by climatic conditions. When the climatic conditions are not good and the weather is not suitable for travel, the number of customers who enter the store will decrease, and people prefer to stay at home rather than go out to eat, resulting in a decrease in the sales volume of fried chicken shops.
