the next step is ads on the inside - they're fighting that. Some parents are upset their kid will be staring at a Pepsi Max ad for 45 minutes every morning and afternoon, and come home and go right for the fridge.
Of course, at every school there are about 6 or 8 "administrative assistants" making $45k a year to wander around the hall with a clipboard and look busy. Brutal waste of $.
I have worked at a university, grocery stores, public schools, law firms, and more... and the biggest waste I ever saw - by far - was when I was teaching. Many teachers squander time, steal resources, and do a shabby job because once they work 3 years, they have a guaranteed job for the next 27 years.
