Ahh... but if you had your own espresso maker and a Coffee Bean & Tea Leaf frother... You would not spend $1,000 a year on morning lattes. But maybe... you like coffee shops.
...and the people who gather there, perhaps!
No, the drink itself is not worth it, and its not exactly the people. Its the environment, the feeling, the ability to get out of the house and change of scenery, and the ability to be served rather than to serve. It is based on emotion, not on taste.... although convenience is sometimes a necessary time factor... if there is not a line at the shop.
