Keep in mind that for a number of people, places like Starbucks and Dunkin create an accessable entry to something beyond a home made pot of Folgers.
I grew up smelling my parents coffee and enjoying the smell, but the taste was horrific so I swore off drinking coffee. Fast forward many years and I dipped my toe into that overly sweet and milky Starbucks and found something that actually tasted good to me. Many years later I have my own grinder and espresso machine, and numerous other coffee gadgets, and might only darken the door of Starbucks/Dunkin a few times a year for convenience. Can I make something at home I enjoy more? Yep. But there’s nothing wrong with other people having other tastes along their coffee journey.
