The types of places that cater to people who order drinks like that will simply replace the coffee portion with an artificially flavored caffeinated syrup. It's the purists who will suffer most, whether it's black coffee, cream and sugar or a traditional espresso drink. I assume your comment is a bit tongue in cheek, and broadly I think you're right. If it was coffee alone, it wouldn't spur people to change. But if it's coffee on top of hotter and drier summers, shorter but more bitterly cold winters and loss of other crop types (even without famine), people might start to take notice. I don't think any one event will swing public consciousness, it will be the sum of many things. I like my coffee but I like my pleasant weather more.mocha cookie crumble frap
