Because Lotte's beverage company Lotte Qixing is the manufacturer of Pepsi. Indeed, Lotte Qixing is the leader of Korean beverage manufacturers, and its business is based on the popular Qixing soda, so the head of the commodity department naturally advocates that "Pepsi should have overwhelming sales in Korea". But this is not enough to be a reason for 7- 1 1 not to sell Coca-Cola, which has a broader sales market all over the world. So I put Coca-Cola on the shelf.
