You know none, and I know several (and used to have that habit myself - I walked past the Starbucks every day on the way to work and would drop in and grab a drink), but the truth lies in the data: Starbucks' gross revenue is more than 25 billion dollars a year. Their US revenue would be 12 cups per year spread across all of the 150 million coffee drinkers in the US, but you already know it's not distributed that way - ergo, there is a heavy tail of frequent Starbucks consumers who purchase daily or more.
