Right, you had previous avenues, and you continue to as well. It's the contexts where someone could feel like their career success could be predicated on sexual capitulation that is increasingly off limits.
The most interesting thread in this whole post is down here at the bottom discussing where and how you can avoid falling into that 1/3! The bookstore in particular might be fair game, not sure. However, I have heard from women that I am friends or acquainted with how annoying it is to be hit on while in public places. The sidewalk, public transit, in line at the grocery store, at the coffee shop, etc. I've heard all of those described as places where a woman is just trying to do her thing and doesn't go there to be accosted by romantic advances.
I don't know if it's true across the board, or just applies to _some_ men, or what, but I know that I personally haven't never felt like I have the go-ahead to approach a woman at the park or something like that.
You just have to open with something deeper than making it clear you want to be in her pants. At best that's boring from being tried by ten other guys that day.
That's why the bookstore example is neat, it gives you an insight into what she cares about. Speaking in broad strokes, women (well, really people in general) want to be treated as individuals with unique, hopes, dreams, and intellectual frameworks.
Also, the bookstore analogy isn't that dated, gen z and millennials are bringing bookstores back. https://www.ingramcontent.com/blog/millennials-have-a-passio...
