Self-service iced coffee

I found a one dollar iced coffee at a convenience store.

The price is only 100 yen but the coffee is roasted and it smells so good.
And of course it tastes good.

How to take the coffee:
Pick a cup with ice up from a refrigerator.
Bring it to a register.
Pay 100 yen at the counter.
Go to coffee server machine.
Put the cup and push a button.
It automatically fill the coffee.

Wmm, American style!
