Long ago, I was on the advertising board of a major restaurant chain. We had a meeting with out advertising agency where they were trying to push some statistics to us about when and where to place some TV ads. Some of us were skeptical and we asked to be given a presentation by the lady who came up with the figures. Before we met her, one of the board members said, "I was told that it always works out that if this person is frumpy and wearing glasses then we should believe her." She was frumpy. Wore glasses. And 100% correct on her TV time buying recommendations.
