People who think that Starbucks has "good coffee" just don't know good coffee. Nothing could possibly be easier than brewing excellent coffee. Starbucks does everything correct, except the crucial first step: selecting excellent "single malt" coffee. Instead, they gather various beans into "blends", and then over-cook them. In the same way that different forms of mediocre, light-weight bread taste the same if you over-toast them, this burnt Starbucks coffee tastes the same at every outlet around the world every hour of the day all year round, regardless of what crop of beans they scrape off the bottom of the price list and combine together.
Long live real coffee! It will help you live long!
