My wife went to my kid's school today to have lunch with my daughter. (Parents are encouraged to come have lunch with their kids.) She brought vegetarian pad thai in a plain white styrofoam container purchased at our local Thai restaurant.
She was reprimanded by the school lunch lady for "bringing in outside food. This place is like a restaurant, you wouldn't bring McDonalds into Mike's" (Well actually I wouldn't be caught eating at either of them). So apparently you can bring your own homemade or store purchased pre-packaged corporate food into their "restaurant", but not food prepared by a third party. (?)
She also said that they have the kids washing the tables (isn't that the job of the custodian/lunch lady?), so when my wife took my daughter to stand away from the table while that was being done, she was further reprimanded by the lunch lady , "You're supposed to remain seated at the table at all times."
No wonder why my wife wants to home school our kid.
