Great idea, poor execution – Muscle Maker Grill Rewards Review

I just used the app for the third time. I've only received credit / points for my purchase once. Today in Lodi, tried to give them the check in code (if I ordered and paid through the app, why do we have to check in???), they told me they don't actually do that here?? What?
