<p>Do you honestly plan on eating at every single meal? I can't really think of a situation where somebody would need unlimited or 18 meals. Keep in mind you'll have days where you don't wanna get up for breakfast, or you have classes during lunch, or you end up going out/getting pizza for dinner.</p>
<p>Mainly people use retail dining as a way of blowing extra meal credits. The stuff is pretty overpriced, to the point that I'd never use it if I had to pay with actual money. But if you have extra meal credits, they disappear at the end of the week anyways, so you might as well use them.</p>
