We've had discussions about this before: Schools' ban on junk food takes bite out of budgets

Same old story:

In high schools around the state, vending machines and student stores can bring in $20,000 to as much as $60,000 a year, depending on the size of the school. Much of that comes from peddling pop, chips and candy.

Without those items, profits at the Lynnwood High student store are down about 40 percent from last year. That means less money for all kinds of student activities, from athletics to debate club. Student governments typically use profits from vending machines and student stores to pay for buses to take sports teams to "away" games, and officials for those games.

I think it was Ben who said that the vending machines are a cure for the symptoms and not the disease.
