Separately, there’s a US tradition of children setting up lemonade stands to make pocket money during the summer. Typically parents help buy the supplies, the idea being that the kids are learning to work for money instead of being just given it outright.
Some US cities have strict permit requirements for selling food & beverage which has lead to silly looking photos/stories of police giving 10 year old kids tickets.
This is basically a publicity stunt by Country Time lemonade.
