I think they show the price for a small cup.
The menu is a moving menu, if you keep eating hang it changes the prices and the sizes of the item continuously. So if you look and it says $2 then $3 the cup size changed. My theory is you saw the small cup price and then it changed to medium and you didn't see the updated price. I don't believe you are being cheated
Things happen once in a while but if you feel that way you should talk to Corporate and get some other ppl that have gotten ripped off
Yup happened to me too
