You don't need to pick up food elsewhere. You can bring a meal with you if your work is too far from restaurant (it's cheaper and healthier to do anyway). It's a meal break not a fucking siesta.

I know this is trouble for the night school sociogy crowd to understand but time where you are permitted to do what you want is but definition free time and that doesn't magically go away because there are practical limitations that prevent you from exercising whatever scenarios it can concoct.

Under you hilariously bad logic my time tonight isn't "free time" because I can't travel anywhere that would prevent me from getting back to work on time in the morning.
