Problem: Loyalty Points Challenge
When I go to a restaurant, I want to collect loyalty points on the money I spend, so I can get free meals for being a frequent customer. Examples: Dunkin app, McDonald's app.

Solution: Customers can purchase food from their home as door delivery & in the restaurant itself. Customers receive loyalty points once they purchase / refer a friend to the app. I have treated Loyalty points as a Wallet Coin. So, this is the solution from myside to the app
