A better carrot?

A new WhichWich franchise opened up near our house and we've enjoyed a few sandwiches there (I recommend the buffalo chicken on wheat).  I picked up a loyalty punch card and you know the drill: buy 10 get 1 free.  Problem is that I walked in there after the first of the year and there's a new sign that says the old cards are no longer being honored or issued anymore.  Sometime in the future, they're supposedly going to implement an electronic loyalty program.  I like the improvement, but can't say much for the implementation.  Unless you've lost focus on your most valuable asset – repeat customers – I think it's a mistake to justify yanking an older dangled carrot from the mouths of your customers by saying the new carrot will be bigger and better.  You're not making good on the first promise, so why should I expect you will make good on the next?  Leaves a bad taste in my mouth.
