>Just kind of musing on a concern I've heard from a lot of people in and mostly outside that field just talking about rules where men can never hit on or anything close women who are professionals.

Then why do couples often say they met at work?

If you're an investor, meeting someone for the first or second time, and someone asks you for money, and you hit on them, you're an utter asshole and moron. Yes, even if someone was dressed in a way that exposed cleavage.

It's not remotely appropriate, professional, or even decent to hit on someone at the place and time that Cantor did.

If you already have a steady, mutual friendship (or other positive relationship) with someone you work with, or are in a casual setting that people go to with the intent of hitting on people or being hit on, then, sure, things can work differently. But that's extremely distant from what occurred here. Someone asking something from you in a professional capacity does not ever want "wanna fuck?" as the answer.
