While on a trip to South Korea, cheerleader girl Milkshake made a risky return after buying banana milk at Incheon Airport. Taking the train to a nearby convenience store near another boarding gate, she found there was no return train. Seeking help from airport staff, they were guided through a special passage and had to pass security again to return. It was mentioned that one must be careful when taking trains within the airport, as different airports have varying rules, and once past immigration, there may be no return trip available.
