I ordered a Sandwich, drink and chips which totaled $12.07. Once I realized that the drink came in a large Styrofoam cup I asked that the order be changed to a medium drink which was a reusable plastic cup. The cashier informed me that I could have the plastic cup, but since she already totaled the order she would have to charge me the higher price and refused to alter my order on the point of sale terminal. I let them keep their twelve dollar sandwich and walked. Who needs a twelve dollar sandwich anyway.
