It's not a petty inconvenience if you are standing at a bus stop at night in the dark waiting for a bus and a creepy guy decides to approach and starts asking the usual nonsense - where have you been,where are you going, do you have a boyfriend, do you live round here, etc etc. Which is a situation most women can relate to.
You're somewhat tied to the bus stop, hopeing the bus comes soon and you can jump on (and he doesn't follow).
If its a well lit, busy bus stop, you can give people around you the side-glance for some back up, or maybe someone will step in to give some support, or maybe it's a busy enough place with enough witnesses, to enable you to feel able to tell him you're feeling tired & don't want chat (or just to fuck off) without fear of reprisals.
If you're stuck in that situation on your own, I a dark place, and that bus you're longing to turn up sails past its so much more stressful.
