Have you ever had a strange experience while using a luggage storage service in Myeongdong? If so, please share your story.

Hello! I'm a foreigner who has been in Korea for a year now. I had a strange experience in Myeongdong. I was trying to use the luggage storage at the subway station before heading to the airport, and it was a bit of a creepy situation. My mom and I were checking the screen when a woman in black clothes with a child stood next to us holding a small carry-on. When we asked them to go first, they just smiled as if they didn't understand, and then a man working at a nearby bag store suddenly came over aggressively offering to help. The man looked really anxious when entering the password, and the woman kept staring at the screen, making me very uncomfortable. I tried to make eye contact, but she avoided it. Even the children were too quiet and seemed to be mimicking her behavior like they had practiced it. It was all so strange that when we insisted on going first, they all stubbornly insisted on going first. In the end, we just said, "Let's just forget it" and left. The man muttered angrily as we left. As soon as we left, the woman and the children also left without doing anything. Has anyone had a similar experience? Any advice would be appreciated!
