7-Eleven's greatest contribution to society is its nacho bar, where you -- and you alone -- get to judge how much cheese and chili to dump on an unfairly small bag of stale chips. Sure, it tastes more like the idea of chili & cheese rather than the actual foods, but dammit, America was started on an idea! Or something.
Shame Rating: 0: Initially, there is no shame in eating nachos, which are perhaps the most perfect food group out there. But when you realize that you have approximately 5min to eat them before the cheese takes over and renders them into flaccid corn discs, your shame level can increase up to 8, especially if you discover you're binge-eating on top of a garbage can on a street corner at 3a.
