Starbucks versus Duncan

Both successful for a few decades, and same coffee business model as far as I can tell. One calls your name, Duncan does not. So do they tend to attract disperate customer bases?  I feel like I don't want them to call my name, now that McDonald's knows my name from each mobile order. But at the same time, I know there's something personal maybe I secretly like it? In some cases?  I seem glad that they don't say it very much, but it is printed on the receipt.
