Buy 5 get 1 free lie

The app will never honor the free mccafe drink of buying 5 get 1 free. I feel like its a joke or someone needs to update their programming on the app so it actually works. Its a waste of time to scan each drink and then never be rewarded with the free one thats promised. It just starts over and over and over. So sad.
