i had to do this in high school too
the food bank is THE MOST FUN PLACE TO VOLUNTEER, EVER...
seriously, you wouldnt think of it, but we had to go there once, and every time since then i would sign up for the food bank whenever we had to do community service. mostly we spent every day putting together these food boxes for families with like 40 different kinds of food in them. like 20 of us would help, and the boxes would roll down a conveyor belt in the middle of the aisle and each of us was responsible for a couple types of food going into the box. we usually had to put together like 3000 boxes, and it got rowdy as hell every time, especially if a few of your friends were there. the boxes would always come too fast for everyone to get everything in on the first try, so people were shooting 3-pointers with boxes of mac n cheese and beef boullion from like 30 feet out...food was flying all over the place, but somehow it worked, soooooo much fun.
