We have work policy that if you are closing with another staff member, you need to make sure they got to their car before you leave.I quite often walk a colleague home, so that might make it a bit more clear. But I've also heard numerous other colleagues and friends describe instances i haven't personally witnessed, just when we've been discussing it.
Either way, we're not generally talking about totally uninvolved strangers. Men who do this shit at pubs and clubs are usually in small groups, their mates who won't get involved but also won't say a thing to stop it.
That's less the case with random instances on the street, admittedly. But the opportunities are there, sometimes, and are rarely taken. A lot of men prefer to just pretend it doesn't happen or its overblown.
It's on street parking so it could be half a km away but I may drive up to them to check this box
