This. When you only get a very minimal lunch break, and zero guarantee of any other break your entire shift (8, 10, or 12 hours), the fucking last thing you want is to spend your meagre "me" time socializing with the people you'll have to see all day anyway. You just want to have your meal, read a book, catch up on FPH, etc. Having to educate fat losers about basic nutritional concepts is not worth the breath it takes.
