I'm a new Colorado resident; I was quite surprised when I saw a full bar at many coffee shops. Asking what's up with the hard liquor, they said it was for shots in ones' coffee, want one? Wow! Growing up in Iowa, with State Liquor stores, and then school in Massachusetts where the puritan attitude still prevents liquor sales on Sunday, and then California where pot is preferred over booze... Colorado has shots in one's coffee from franchised coffee shops, what a world.
