<p>If you live in the dorms you don’t really need to worry about roommates eating your food. Fridges in dorms are there for storing leftovers and drinks. In my case, at least, there were rarely any left overs and the fridge just held drinks and a pitcher of water. </p>
<p>It’s really selfish and kind of shows almost no forethought to say you won’t share. Rooms can’t hold more than one fridge and having more than one microwave is kind of pushing it. If you set ground rules (in a non-jerk manner) in the first week or so you shouldn’t have a problem with stuff. I had a horrible idiot for a roommate my first year (I have nothing positive to say about her) and even then I never had a problem with food being stolen.</p>
