"slightly intimidating" 
These things are all part of a wider social context of men dominating women. Each little thing may seem trivial, but it can't be divorced from its wider context.
Here's an example: do women routinely do these things to men? No, they don't. That's the difference.
Here's another: I was walking to a hospital to have a D&C because my ten week-old foetus had died. A builder shouted out: "Cheer up, love, it might never happen."
Of course he could not have known my circumstances, but would he have said this to a man? Not likely. Did he he do this because I was a woman and it was part of the wider context of being able to intrude on women? Very likely.
The question remains, would any woman's life be damaged by never having a a strange man give his uninvited views?
By the way, if I could travel back in time, I'd take a baseball bat to him. Just saying.
