If Dominoes sent you a coupon for their new and more delicious pizza, but you hadn't received the one you ordered a week ago, would you spend more money with them on a different pizza?

As my father said, once upon a time when I put another quarter in a Coke machine that didn't give me a Coke for the first quarter, "Son, don't ever put good money on top of bad money."

I lost my second quarter too, and in the end had no Coke.
