Giving way to the elderly?

I was at the gate of the car park to a hypermarket yesterday at 11 am. A car near the gate was backing out. So I had to wait. It was not the ideal location, but since he backed up I conveniently parked in the same lot that he vacated. Just as I locked my car, a young Chinese man in his late 20s, walked up to me angrily and said " I waited for the lot, it is mine". "Where did you wait? I asked. "That side", he said pointing to the side. I went back into the car, backed off and parked myself 3 parking lots away. Then I looked around. Being 11 in the morning, there were still alot of parking lots available. I walked up to the young man who had also parked. I said "You not malu (ashamed) meh..fighting for a space with an old woman?" . He just stared at me without saying a word, maybe stunned. I walked away. I wonder if he had learnt something.
