I think it depends on the level of fame. Zuckerberg/Gates/Buffet/Musk all have bodyguards. Pretty sure I could walk past EG the Coinbase or AirBnB founders and not recognise them.

I saw benioff crossing the street in San Fran once. Heh it looked like that painting of Washington crossing the Delaware. My CEO was with me at the time and in awe, I was laughing so hard I had to stop walking.

I'm 90% sure I saw Michael Bloomberg walking about in Canary Wharf one morning. This would have been around 2015-ish. No security at all.

The other thing that makes me think it was him is that Bloomberg looked like they had setup an outside broadcast in one of the squares there as well.
