Cheaper Sandwiches
The unfortunate thing about college is that even eating can become an expensive affair unless you find a loophole like this guy did. Apparently, the deli on his campus charged $8 for a regular turkey sandwich which is way too much. The salad bar, on the other hand, was reasonably priced to promote healthy eating.
The OP figured out that the salad bar had all the sandwich ingredients, except the meat was shredded. The deli would also sell slices of bread for $0.25 each, so he came up with a plan. He would get the salad and bread separately and just make his own sandwich for less than $2. Oh yeah!
