If I was the girl scout leader and My troop was selling cookies in a public place selling to the general public, I would have called the town hall and asked(better safe than sorry). Not only that, a girl scout leader should be setting a good example for her troop, when in doubt inquire, there is no expense involved in asking. Make sure the whole troop is involved from beginning to end(this includes asking one of the girls to call the town office and ask). I was a girl scout for nine years. Scouting is more than baking cookies and making crafts!!
