It's the same way ofthinking as a luxuory hotel. There's a groom bringing your luggages to your suite, not a sophisticated warehouse style system shuffling them

It's the same way ofthinking as a luxuory hotel. There's a groom bringing your luggages to your suite, not a sophisticated warehouse style system shuffling them around. Having a guy/girl fill in the tank at the station is not efficient, but it makes a better service experience, it' also less error prone and stress free. BTW most people 'standing there doing nothing but X' in Japan are actually very valuable and can help you in a lot of matters, even completely unrelated to X. Unefficient but priceless if you have a special need or just don't know how things work.
