Apparently as a thank you to the kids for their School Community Association (SCA) fundraising efforts the entire school was "rewarded" with an SCA funded lunch from McDonalds.
Because what better way to spend the money kids have raised for their school than on cheeseburgers, hamburgers and chicken nuggets, and what better message could there be for kids than McDonald's is a reward for a job well done?
Of course parents could just say, "no". It's not as if your child would feel different, left out or be picked on because he or she pulled out a brown bag while everyone else in the entire school tucked into their burgers, right?
