That's a smart cookie! An unidentified 9-year-old girl sold more than 300 boxes of Girl Scout cookies in six hours outside a marijuana dispensary in San Diego on Saturday, spurring debate about whether it violated Girl Scout rules. Her sales tactic of catering to munchies-prone customers raised some eyebrows. Scouts may not sell on private commercial properties or sites used by the general public. However, this situation fell into a gray area because the girl didn't set up a booth outside the store; she cruised the sidewalk with boxes of cookies in a wagon, according to local reports. In a poll, most respondants sided with the enterprising Scout.
