I worked for Rush for about three days. Just enough time to see behind the scenes. There is corn syrup in the lemonade mix, and a bunch of other hidden ingredients that they intentionally hide. The owner is a slimy business man looking to capitalize on the green and organic food movement. He uses Styrofoam, and backs it up with lies about how it's actually good to use it, how it's better than plastic or paper, and how it could potentially help the environment. Look it up yourself. Styrofoam is not a good idea.
Cons: styrofoam, arrogant staff, corn syrup
