This reminds me of the time we had a fire drill here.
I live in a boarding school meaning we aren't allowed out after 10:30 or so. This one night we all got drunk and went to bed. My friend however was hungry and snuck out to buy a Big Mac.
Unfortunately we had a fire drill, and when our House master was taking the register my friend just casually strolled in from town with a McDonald's happy meal box! It was freaking hilarious. He got suspended however so the moral of the story is: McDonald's is unhealthy.
Oh about your school, what a shame...
