When you buy Shaopao in the Philippine Seven Eleven, you will take it out by yourself from the showcase by using the tong. And you put it in wrapping paper and bring it to the cash register, then pay the price.
In a convenience store in Japan, when you order at the cash register, the clerk picks it and hands it in wrapping paper and bags.
By the way, at a convenience store sell Nikuman for about 120 yen. Depending on the shops, they sell more higher grade and expensive items.
