Drip coffee in convenience store

In the Philippines’ 7-Eleven, we operate the machine ourself and drip coffee into the cup prepared, then pay at the cash register. But it is different in Japanese convenience store. In Seven Eleven and Family Mart, we buy an empty cup at the cash register, then operate the machine ourself and drip coffee into it. At Lawson, when we order coffee at the cash register, a clerk drip coffee into the cup and offer us.

Incidentally, it is the same for shao pao. In the Philippines, We put it on a wrapping paper by ourself and bring it to a cash register. But in Japan, a clerk will offer it after putting it in wrapping paper.
