Not to mention that many colleges have rules about what appliances can and cannot be used in a dorm room/dorms in general. Depending on the school, George Foremans and waffle makers may be banned. And at most colleges, microwaving popcorn is enough to set off a fire alarm. You don't want to be the one that caused the dorm to be evacuated at 3am because you were making waffle maker pizzas.
I would have laughed my arse off if Ree's Caesar dressing was made completely from condiment packets snarfed from a dining hall. Admit it, that's the only way most college students will access mayo, hot sauce & S/P.
Also, if Ree's daughter is now in a sorority and/or living in a sorority house, do we really think she's making Caesar ala Ziplock? Don't most fancy sorority houses have their own dining staff?
