The girls at my LV counter are incredible. They are so patient with me, they are very knowledgable, and they give me just enough encouragement to make a decision. I tell them all the time how much I appreciate their help but I want to do more. Can I write a letter to their superior to say how good they are so they can get a pat on the back from higher up? If so, who do I mail it to? Does anyone else have a suggestion?
