The review feedback program sounds like over engineered nonsense. You get metrics which you think represents customer experience which you can use to evaluate and motivate your employees to act a certain in this coffee fueled skinner box designed to train baristas. But the data won't represent that, the interaction with a barista is only a small fraction of what makes a coffee shop good (first should be good coffee, second probably a nice place to sit). And the obvious conclusion is that the barista tells the customer, "if you want to leave a tip please give me a 5 star rating, my salary is based on ratings." So now you just have tipping with extra steps.
