How to make your customers loyal, in a quick and easy way?
Tip #1: Promise something extraordinary. "You're dining in the #2 fastest restaurant in the world!"
Tip #2: Let your customers prove it. "Order and you'll get it in 15 minutes!"
Tip #3: When you fail, reward your customers. "...or you get our Yummy Dessert for Free!"
Result: Your loyal customers will come to your restaurant everyday, waiting the moment when they'll finally get your yummy dessert! (And yes, you'll actually give it to them sometimes, please.)
