I had something similar happen to me in Miami about a decade ago. As a New Yorker I'm just used to walking and taking public transit everywhere. I was down there for some data center work I needed to do out of the NAP of the Americas, and one night I decided to go to see a friend of a friend DJ at some bar in downtown Miami. So I took the free Miami elevated train to a stop near the club (The Vagabond) and started walking over. I get a block into the walk and someone pulls up on a bike and is like "wtf are you doing? are you lost? you should not be walking right now, do you need help?". It was a totally fine walk, maybe 5 minutes at NYC walking speeds, if maybe a bit desolate. The guy proceeded to slowly ride next to me while I walked to make sure I was ok. Ended up buying him a beer in the club and chatting for a while, he just thought it was dangerous to be walking.
