Have you ever had the experience of receiving a seat on the subway? What about you?

Today, for the first time, I received a seat on the subway. I've seen many posts lately saying that people don't often give up their seats, but today I had a truly grateful experience. I always give up my seat for the elderly or people with disabilities, but I never thought I would receive such an opportunity since I'm a healthy person. However, today at Gangnam Station, an older gentleman offered me his seat. When I feel that kindness is lacking in the world, the saying that we should be that kindness comes to mind. Have you had similar experiences? Or what do you think about the culture of giving up seats on the subway?
