A cheaper way to eat healthier

While Dan was in Waterloo he was staying in a room at the hospital. There was a kitchenette down the hall with a microwave and a fridge. Dan was trying to come up with ways that he could eat healthier and cheaper instead of going out and eating in the cafeteria. He decided to go to a thrift store to see if he could find a sandwich maker or something to could make something other than microwave meals. He found this cup .  .   .

When he saw the cup he remembered that if you had your own cup refills at the hospital was .50 instead of $1.50 and the physician's lounge had free sodas if you had your own cup.  Sometimes I think it fits.  .  .  .
