It easy to see why, the burgers are getting smaller and the prices are going up. The dollar menu is now full of smaller burgers and fries that cost at least $2, they are served luke warm, half the time the order is wrong, and every soda and juice you get from them is watered down. I stopped eating there when I got an orange juice that was nothing but water and orange colouring, it had no taste and they had the nerve to charge me over three bucks for it. I can get half a gallon of juice at the market for half that price. Also the price of a mean there now runs between $7-$11, if I am going to pay that I will go to subway where I am not getting a heart attack to go, or Hardies where I can get a real burger for that price.

Bottom line they jacked up their prices while reducing quality, since when has that worked for any company in history? You would think they would start teaching a class in business school that tells would be CEOs that this is a bad idea that will kill your company in the long run.
