My personal opinion is that people who want to save money dont go to starbux or any restaraunt and those who want convenience already had it previously thus Verismo customers are not starbux store customers anyway. Since startbux began people keep making the mistake of thinking that its all about the coffee. It is not. At least 50% if not closer to 75% of sbux clients are not there because of coffee but rather because of social atmosphere. Sbux attracts several types of people, those who want a relaxing hang-out with friends, students who just want a quiet study, business people who want to get out of the office and relax a bit or maybe meet a client in an informal setting, people who hate alcohol and bars and want some other place to hang out, etc. None of these people are there for coffee specifically. They buy the coffee in order to hang out there. This is why other brands are not able to compete and why I think you are wrong in your analysis. Sbux is a venue service provider wrapped in a restaurant package. Verismo will have near 0 affect on their restaurant business.
Now ask me whether or not I think they continue their hot growth and I would have to pause. I am not sure which is why I have not bought in. Keeping a close eye on this, INTC, and a few mREITs.
