I suppose it's partly a function of not really caring that much about caffeine in the morning although I do usually make coffee at home. But when I'm traveling and could even put a Starbucks latte on my expense account if I wanted to, a good part of the time I see the line of people out the door and just keep walking.
I don't think so. When I quit smoking, I had to consciously make the decision not to buy cigarettes every time I was at the checkout in a super market. That went away after about two weeks. For a few months that followed, I'd stand there thinking "and buy some cigarettes" and then I'd realize I didn't smoke anymore.
I doubt that getting off of the latte-habit takes longer than getting off of cigarettes.
Another question is whether small sugary treats are a good thing in general. Again the cigarettes as a comparison: cigarettes are the best when you haven't smoked for a day. But that's because you're suffering withdrawal, not because they're that great.
