All the time.... whenever I see a woman, elderly, handicapped or very young children, I usually give up my seats on the train to them. This is courtesy. I always volunteered to give up my train seat all the time to people in need. However, it's when males fighting against males....where we compete for the seats. I remembered one time I was on a crowded train, and there was one seat available in the middle of the train. There were two big men. Each guy from opposite ends of the train ran toward the open seat. And we got there, they fought and shoved at each other for the seat. It was so funny to watch two grown mature men hitting and punching each other for the seat, so several the passengers including myself had to separate the two men. The conductor kicked both men off the train for disorderly conduct. LOL
