A group of middle-aged and elderly people after the square dance most want to buy what please help!

The middle-aged and elderly people who dance at night usually do not spend more. After jumping all home. And the square jumping people are basically living in the neighborhood, thirsty, hungry, home are solved. Try selling watermelons in this weather. Older people only buy these. After the dance, take a watermelon home. I suggest you change the place.
