OK, I'll try to work this out for you.
First. If I let you do it, I'm going to have to let everyone do it. Lets just assume that a dorm room hold two and they can get along well enough to do joint meals between them. (which is about the most awesome assumption I've ever made, hell, we couldn't even agree on what kind of beer to stock.) And speaking of beer, as I recall my dorm fridge (and I have one in the crew room at work, so I know this is still true) can hold a little bit over a 12 pack, but not quite a case of beer. Which is not enough 'fridge space for two people to live on. I am going to assume too - and this is not a reach - that most college kids don't know much about cooking, hell, its all they can do to get the laundry done. So, if you're going to do a heavy microwave deal, you'll need a real freezer, so now, I'm putting a full fridge in every room. And a microwave, and some sort of hot plate.
Since people are conditioned - like Pavlov's dog - most are going to eat about the same time, so the peek usage is going to be heavy. The peek is going to come in two ways. First, everyone is going to open those fridges at about the same time, hence all the motors and compressors (very heavy draw) are going to all kick on about the same time. Which is also the same time that all the hot plates and microwaves are going to go on. That draw is huge. HUGE. (and I am a certified electrician, so I think I know what I'm talking about) Though the electrical works can handle a lot, I bet they are not near enough for this level of draw. And the requirement of electrical power require it to be able to handle the peek (with a little headroom) - so for me I have to calculate how much juice I'm going to need if (and when, and there will be a when) the sound system is pushing max and the amps are on full draw, and all the stuff on stage is going to be on, and all the lights are going to be on 100% power. If I can't do that with a 10% headroom, then I need to bring in a jenny and use it to cover. At one theater its never a problem. At the Fillmore, if we're going to be shooting a DVD and using the TV lights too, its jenny time.
So, that's the power deal.
But, where are you going to wash all that stuff? How are you going to dispose of the excess food material, which if left to its own is going to draw ants, roaches and rats like a panty sale at VS draws CDs. Major health issues there, hence the involvement of the health department, who can be just as bad as the fire marshal. (both have the absolute power to shut down something until a major problem is fixed - that's everyone in the dorms out in the streets just because the hippie philosophy majors down the hall thought they would live out Alice's Restaurant in their dorm room and not take out the garbage for a long time.) Sure, you are responsible, but is everyone? No.
Do you even have the room - much less the cash - to equip even a minor kitchen? The pots, pans, tableware and implements of kitchen destruction. Plus you need all of them other items - including, but not limited to: salt, pepper, sugar, baking soda, baking powder (not the same things) flour, pancake mix and spices. Even for crappy stuff, your looking at a couple of hundred dollars - and for the good stuff, a thousand easy.
Oh, and cooking is messy. Are the rooms vented for this? No. Is all this stuff going to stick the the walls and get into the carpets and drapes? Yes. So I'm also going to hit you with like a $500 clean up charge.
So, how much you saving now?
I'll leave you with the immortal words of Frank Zappa - the inventor of the burnt wennie sandwich, which I guess you'd be eating a lot of...
The dangerous kitchen
If it ain't one thing it's another
In the middle of the night when you get home
The bread things are all dry 'n' scratchy
The meat thing
Where the cats ate through the paper
The can things with the sharp little edges
That can cut your fingers when you're not looking
The soft little things on the floor that you step on
They can all be dangerous
Sometimes
The milk can hurt you
(if you put it on your cereal
Before you smell the plastic container)
And the stuff in the strainer
Has a mind of it's own
So be very careful
In the dangerous kitchen
When the night time has fallen,
And the roaches are crawlin'
In the kitchen of danger
You can feel like a stranger
The bananaes are black
The got flies in the back
And also the chicken
In the dish with the foil
Where the cream is all clabbered
And the salad is frightful
Your return in the evening
Can be less than delightful
You must walk very careful
You must not lean against it
It can get on you clothing
It can follow you in
As you walk to the bedroom
And you take all your clothes off
While you're sleeping
It crawls off
It gets in your bed
It could get on your face then
It could eat your complexion
You could die from the danger
Of the dangerous kitchen
Who the ->-bleeped-<- wants to clean it?
It's disgusting and dirty
The sponge on the drainer
Is stinky and squirty
If you squeeze it when you wipe up
What you get on your hands then
Could un-balance your glands and
Make you blind or whatever
In the dangerous kitchen
At my house tonight
