I was out riding my bike this morning when I passed an older guy who was also riding. He had a bike that looked like it was equipped for utility. So I called out “Good morning!” and he responded, “Ni hao!”
That may qualify as the first time in history I have been “nihaoed” by a stranger who was also Asian.
Anyway, I responded, “Ni hao!” and he came to a sudden, screeching halt and stared at me. Then the questions started. We talked briefly (briefly, because all I can do is briefly) before parting ways. I suspect he must have experience speaking with non-native Chinese speakers because he spoke very clearly and used small words.
