New web-based services allow moms to prepay for cafeteria food, specify what their kid can and can't buy, and go online to track his purchases." From the article: "If the child tries to buy a prohibited item, an alert flashes on the cashier's computer. Of course, the system isn't foolproof. According to a KRC Research survey, 73 percent of 8- to 12-year-olds are throwing out part of their lunches at least once a week; 36 percent are trading them." All I ever got was PB&J.
