I think we can blame a lot of the problems in the US coffee market on the damn 'to-go' cup. People are not tasting their drinks, they're in a rush, they order those horrid 'extra-hot' drinks... the list goes on and on.
Bronwen makes a great point. Coffee bars are social centers in so many other parts of the world. And, in many cases, they were started to fulfill this same function in the US. But now we have people talking on their cell phone while grabbing a drink to take with them in the car.
There are so many things wrong with the picture, and regardless of whether or not 'to-go' cups are the cause - I have little doubt that killing them off would fix a whole bunch of the problems. And even if they only fixed a little bit - they are such a potent sign of what is wrong here that making them go away would send such a clear message it would be well worth it.
Death to the 'To-Go' Cup Now!
