Lunchroom Expectations

We had a SAD SAD DAY in the lunch room today!!! … I was told of students not only getting up out of their seats when they are to remain seated until lunch time is finished (unless they need something at which time they need to raise their hand), but that they were also throwing food.  Sadly, our Lunchroom staff had to move some of the offenders to other tables. I would really appreciate it if you would visit with your student about what your expectations are as will I.  Thanks so much for your help with this matter.
