How to shop!

Some things in Japan you buy ower the counter, and some not. Example, when you travel by the Metro, you first buy your cupon in a vending machine out side, then you pass the metro gates through putting your ticket in on one side, and getting it back on the other side. Then you need the ticket on the station to get out. Clever. No need to argue. And so its at some food places, and even hotels. Theres a light for what is avaliable. Look close.
Paying for a hotelroom. (sorry the pict, is reaaallly bad)
A food place, with a cupon machine. just hand in the cupon, and Voila, you get your food. Its not gourmet, but its fast.
