Around where i live, the city busted 2 little girls with a lemonade stand. They had no business permit or permit to sell food. there parents were fined.
That also happened around here. The local city require a permit or license for damn near everything. A few years ago, a girl set up a lemonade stand. A neighbor called complaining the stand wasn't permitted.
Police had no choice but to force the girl to close the stand and write a ticket to the parental units. Police at that time even went on record saying they wouldn't have done anything if no one complained as they would rather deal with, "real", criminals.
IIRC a local restaurant owner was pissed over the story and opted to give the girl free run of his restaurant for a day complete with a full staff selling lemonade. I think it's a big annual charity now with several restaurants jumping on board.
