A man sitting next to me on the KTX said something while eating...

This is car 1*, and a man told me I needed to go to the next car, so I moved. Now, the person sitting next to me appears to be a woman in her 20s or 30s, possibly an office worker or a civil servant, sleeping peacefully. It's been a while since I rode in a KTX standard class instead of the deluxe class, so this kind of happening occurred.
