Real life scenario, how would you respond?

Now I'm a retired 60 something, I'd hope I'd be brave enough to say what I saw. I have no job to lose now.

Yep me too I would do this if it happened to me IRL. It hasn't yet but yeah, I'm not into confrontation anyway generally so would just get myself out of any sort of situation where that might happen. I've been sexually assaulted, thankfully I was rescued before it was rape but it was in women's toilets. Years ago, when I was very young. He followed me in, threw me into cubicle, locked the door. I was drunk, unable to fight back. Another women noticed him following me in and ran after then banged on door, shamed him enough he unlocked it and stormed out. It was at a noisy, bar/restaurant in a posh resort.

It's one of the reasons I really hate the toilets that say "cubicles" and "cubicles with urinals". Men get two choices, also any man going into the one marked "cubicles" and following a women in would no longer be questioned. It's a safeguarding failure. It's why I won't go back to five march in Glasgow. I actually had a bit of a panic attack when I saw their toilets. It was quite a posh bar/restaurant I was assaulted in (as five march also is). So it's not a stupid reaction to have.

When encountering a larger, stronger male who is deliberately transgressing boundaries, I get out and away as fast and quietly as possible. Grey rock, get out.
