Maybe you were at a coffee shop and when your turn came, you opened your payment app, tapped your phone on the payment device, grabbed your cappuccino, and were done. Quick and easy. Maybe too quick and easy. Did the coffee shop miss a chance to engage with you? Did Mastercard miss an opportunity to show how their brand made this "priceless" moment possible? Did you miss an opportunity to teach your 8-year-old daughter a lesson on the value of money?
