A few weeks ago, I wrote about my frustration with the local DQ's poor customer service here. To my surprise, I received a letter from DQ's headquarters in Minnesota apologizing for the bad experience and a promise to investigate and provide necessary training to ensure this doesn't happen again.
I know it's probably a stock letter which they probably only updated with my name and address. But, that I received it means that someone up the chain read it, indicating there is a chance it will be addressed with the local DQ, which is gratifying.
In retrospect, I now believe I handled the situation appropriately. In the words of Edward Bulwer-Lytton, the pen is mightier than the sword. And this is the lesson I want my children to learn.
