my daughter was a brownie and sold GS cookies up to a year or so ago. Yes, you deliver only what has been ordered, but the troops themselves can order more than that and they will set up (with permission) in front of the Safeway or elsewhere, with a table and sell cookies on the spot. i have NEVER seen anyone set up in a neighborhood though. it is generally in a commercial strip area and the troop has to obtain permission.
Somehow I doubt that this Dad came by his cookies in this manner, if you know what I'm sayin'...
Anyway, a Girl Scout memory just came floating back to me. My mom was the troop leader, found out one of the girls had deliberately gone out selling cookies a day earlier than was allowed (so she'd get more orders and win the silly contest), and decided that the punishment for cheating would be to bar her from coming aong on our camping trip. Girl's mother objected to her darling daughter being punished in any way, and pulled her out of the troop altogether. This was in the sixties, so I guess bad attitudes aren't new.
