They are definitely cool with it. I think Americans and a lot of the world are consumers out of convenience, whereas (for coffee and other similar goods) people in Japan are consumers for the experience. I think the choosing portion is a part of this experience that they're there for. Just a hypothesis, though.
> The points you make are valid. I think people perceive Japan as a high tech country because they have a highly developed and efficient transit system. I mean when you go there as a tourist, that's practically what you are interacting with. Oh, and high speed Internet. That certainly will strike the average person as a high tech country.
Transit is amazing here. Except when it rains, it seems to cause the local trains some trouble, which is unexpected. My internet experience has been hit or miss, but work and cafe speeds are amazing here. Not Seoul amazing, but solid.
