Week 2

I had my first disciplinary confrontation this past week with a student in my Marketing class. 
There was a student that had his phone out and I asked him to " put it away " .
The student responded " I'm coping my notes". I responded " put away your phone". This student was obviously not taking notes because during lecture. He was not writing anything down. He had a sarcastic tone as well. 
He then stated " Fu***** Teachers".  In front of the entire class of 20 students. He then slammed his laptop down and proceeded to put it back on the laptop cart. When he got back to his desk I told the student "it was not personal" but the student just seemed to ignore me.  
I spoke with my co-op teacher about the issue and she said to give him a lunch detention.Which in my opinion was a bit on the lighter side of punishment but you do not want to lose the student entirely for an overly harsh punishment.
