Selling is, sadly enough, a very useful skill in this world. BUT, as cantlogin pointed out, these activities are 99% handouts. There is no way that anyone would buy $0.2 worth of popcorn for $10 unless they really liked the colorful tin it comes in, or they felt obligated.
What burns me is how trivial the amount of money turns out to be in most cases. The PTA at our school was boasting how their fundraising brought in $12,000. This school has a budget of $3-4 million! What a colossal waste of time!
Iím also annoyed with the implication that I should be funding someone elseís hobbies. I donít walk around the neighborhood asking everyone to contribute to our family vacations or my new guitar, and I donít feel like contributing for theirs either.
